    I'm not sure requesting investment advices on a forum is a good idea. You have half a million bucks - maybe request the help of a professional or use your own time to do some research and see what your best option should be?

    Bitcoin has always stayed up the most and the best. Besides this, nobody really knows an accurate answer to how much we should wait or how deep a dip will look like in the current market conditions. Crypto markets are new. We're still early birds, and the conditions of the market change second by second..

    Hello

    Now BTC is 56 450$  ...

    everyone say buy at the dip but it is a dip or correction ..10 % ? down 20% ? 30 % ? 40%?

    sorry i am sure you have answer this question of thousand of time but now we new compagnies buying btc must impact the price then for strategy today not same as yesterday ...

    i was here in  2017 , AND WAS VERY STUPID not listen and invest in 100% alt   after correction in 2018  i decide to leave my position and hibernate really stoping completely leaving all in a hard wallet..not look news really. came again in  now in march 2018  ... and was lucky to invest in few alt not too bad but a lot in shit coins ..yes you laugh guys ...  so i just did a X3   .... i came back with a 8 BTC  of altcoins and my delta app tell me i will be 56 BTC if i just invest BTC.... so laugh again

    and then now i have 450K usD.. save 150 K and want to go back wtih 300K USD ..how you will invest it ?  10%.. till a big dip .. or full now and pray for the correction not coming ...
    or just be patient and wait the famous correction ..... when it is a good entry point  ?
    all that to say that i dont want do same mistake , and need your help ...you laughed so help now :p

    also wallet i Know i should do 100 % BTC or little bit ETH ... but it is a drug i think the alt and i know i will go back so what the max in % you think i should invest ...
    thanks  for your time
    Avoid altcoins, altcoins are just there to speculate with them and nothing more you already tried that route and failed, you still have a lot of capital and that is what you should use, for what I can see I do not see the bull run slowing down so right now seems like a good movement to buy, but at the end it is your decision, no matter what you do this decision is going to shape your life, if you do not invest and bitcoin skyrockets then you lose on generational wealth, but if you invest and the market goes down you could lose money if you sell too early.

    The established alts, such as ETH and ADA made the recovery, but the smaller alts and tokens never recovered from the slump in 2018. Most of them are now dead or dormant.
    Some of the alts that showed potential never recovered and there is no hope whether we will have any decent profit as some of projects stopped developing when the market went down.

    @OP It is not the best time to invest as all the markets are rallying at an all time high valuation, like everyone mentioned we saw rally recently in BNB and ETH might rally even though the transaction charges are high.

    The price of Bitcoin is now very high, and some of the top altcoins are now very high. But many people ask what is the right strategy to buy
    at the dip, If we look at the performance of Bitcoin and altcoins you may have to wait a little longer if we want to buy at a dip. My advice if
    we wants a long-term investment can buy at the current price and HODL at least 3 years. Then for those who want short-term investments,
    wait for the price of the coins we want to buy to drop by about 20%. But don't use all the capital we have, in case the coins we buy drop lower,
    we can buy them again.

    Back in 2017, much of the focus was on altcoins as there was an ICO boom. But the same altcoins, which gave 100x or 200x returns during the first half of 2017 went down by as much as 95% or even 99% in 2018. Almost everyone ended up with losses, and some of my tokens and alts also went down by a lot. The established alts, such as ETH and ADA made the recovery, but the smaller alts and tokens never recovered from the slump in 2018. Most of them are now dead or dormant.
    yes indeed never again ICO Sad. ...
    but i still believe in alt .. thanks for all your answer even the one critics Grin  ...it is good to hear

    One good thing about Bitcoin is that even it falls, it will still test that point you bought it. Though, it take time atimes. Buying it now is not bad to me. I am not scared of the price at all. To me, Bitcoin is a worthy asset.

    The "top" alts now account for more than 60% of the altcoin market share. I am talking about three of the top altcoins - Cardano, Ethereum and Binance Coin. These three account for a market cap of close to $300 billion out of the total altcoin market cap of $500 billion. A few years back, I had predicted this. There will be a consolidation in the cryptocurrency sector, with only Bitcoin and a few of the top alts managing to survive. And that is happening now. Despite the rally, the smaller altcoins are dying out.

    When we make a profit, we are greedy and keep buying with the trend.  That would reduce the good position we hold.  When the market reverses, losses are inevitable.  Investors often lose all profits.  I have a little experience of buying cryptocurrencies with a small cap and good growth potential.  Whenever there is a profit, withdraw your capital and step into another crypto. Just do so you will not be deeply sunk with an altcoin at all.
    I usually do when my altcoin x2 or x3 I will sell them and take the money invested. Buy very little for each different altcoin.

    i dont clearly get what you are trying to ask, but i will say there is difference between the bull run of 2017 and this time. a common mistake that majority of people made then is that they refuse to aknowledge the dip and cut losses as man people just bought into BTC then to milk the market with the hope of it going higher continuously. this time we have institutions, top individuals that have bought into bitcoin. but always remember that the dip will always be there and your job is to recognize it.

    Best advice is put any cash you don't need for spending or savings mostly into bitcoin. You can put some into Eth, but only a few percent into alts, and plan to get out of most alts before the peak hits.

    Everyone is making their mistakes and have experienced regrets especially way back 2017 after the big hype of the first attained ATH when people have been getting into crypto in a massive volume and all turns out to have been disappointed with the sudden down early the next year 2018. But we ought to learn from those mistakes and make it a way to deal with the past and make our move on doing what we must do to grow up and move on. Now that you basically know what mistake you have done before, you can use of the information to make your decisions better on deciding to put barely big percent of capital into Bitcoin and some into valuable altcoins that you think can give you potential of earning.

    As such I don't have anything against the altcoins. There are very good altcoins in the market such as Cardano, which in terms of technology are much ahead of Bitcoin. The same can be said about Ethereum, BNB, Litecoin, Monero, USDT.etc. I have problem only with the shitcoins, which have plagiarized white papers and stolen algorithm, and no practical usage. Unfortunately, out of the 10,000 plus altcoins, 95% to 99% can be classified as altcoins.

     all that to say that i dont want do same mistake , and need your help ...you laughed so help now :p
     

     Look, it's all up to your belief. If you believe bitcoin will still go up and you've seen how far bitcoin can go just like the price of it from 2017 to 2021 with massive growth then you can just wait for another dip before investing and buying it. Just do not panic when you bought at $50k and it went down to $40k. As I can see your emotions were easily get dragged by the fall back market.
     
     On the other hand, you can also diversify and put half of your capital in different kind of altcoins like eth, bnb, ltc and with the other defi coins that are booming lately.

    If you look at the cryptocurrency market cap, around 95% is made up of Bitcoin and a handful of the top altcoins. The remaining 5% accounts for the smaller altcoins and tokens, which may number somewhere around 5,000-10,000. DOGE doesn't deserve the market cap it is having right now. It doesn't have any practical usage, as it was created in order to mock Bitcoin. And such cryptocurrencies will not last for very long. Those who invest in DOGE will regret about their decision later.

    Well, when you choose to invest is best known to you but, praying for the correction not to come is of no use and certainly, when the time is right the correction would always come, its always a matter of time. Not buying at ATH positions has always been the wrong way to go about investing so, you've got to wait should it be that, your avoiding your previous experience with investing.
    Though, bitcoin is very different from altcoin and should you exercise a little patience, you would always get a return in no time.
    The good news now is, the bulls are doing their best in strengthening there position after every little correction so, you could just invest at such peril times than jumping in the market as it pleases you @OP.

    You don't need to mind those "companies" you mentioned. They could be impacting the price a tiny bit because probably they're gonna buy in bulk as always as they're company not an individuals, but that shouldn't bother you.
    Just invest when you have the coins.
    Your hibernation in 2017 really did something, but you might have missed a bit that year because that was like one of the memorable ATH of BTC back then before it crashed.

    Best advice is put any cash you don't need for spending or savings mostly into bitcoin. You can put some into Eth, but only a few percent into alts, and plan to get out of most alts before the peak hits.


    But not all of the cash because if the price increases and you buy bitcoin at the current price, you can get trap buying bitcoin at a high price. Maybe you need to wait for a while until the price is down to buy it at a low price and I think that will be safe for you. Buying some ethereum can be a good idea as long as the price is at a downtrend. The altcoin will get the time to increase, so that will be a good time for you to sell your altcoin and convert it into bitcoin.

    the 2018, 2019, 2020 dump of the altcoins should have already given you more than enough experience no never invest in any of the altcoins for long term. they are always going to get dumped sooner or later even if their pumping lasts for some time like it did back in 2017.

    if you want long term investment you should always stick to bitcoin and nothing else.
    There is a FOMO brewing...
