Maybe the only thing I can say is that as long as you have the opportunity to buy Bitcoin right now, do it. Don't wait for it to move up quickly when you decide to buy it. Believe me, don't be like others who only decide to buy when the price of bitcoin is too high.

And I also think it will happen a few months from now. It seems that we are already in the countdown to the approaching bull run, to be honest. This is what I see and observe now.

OP those that bought in December last year assumed that the price was high and now they are gaining in the market, so to me I don't think that there is a particular time to invest in bitcoin though there is a suggestion that investors should buy when there is drop in the price but what if you continue waiting for price drop and it ain't coming, what will you do, will you just abandon your investment plan when you are set for it, when an investor has his fund ready for investment he should not give up because of the price increase because such opportunity may not present itself again, the price he is afraid of may continue to skyrocket and he will blame himself for whatever wrong choice he made.

Never back away from a good investment because the price is high, the good thing with Bitcoin is that you can buy fractions.
What you need is a strategy, it can be DCA, it can be one shots, you will have to find what suits you depending on your means and what you want for the future.

Do you believe in it ? I do and I don't even look at the price anymore.

If you don't have enough money to invest in Bitcoin and you choose to use your emergency money, take a loan etc in order to invest in Bitcoin because you believe you can double or triple your money in the next year, I suggest you shouldn't doing that.

There's no guarantees you will earn in the next year, moreover it's better to buy Bitcoin because of the value instead of the price.

So OP, what price do you want to buy Bitcoin at? $30k? well there is a very good chance
that $30k will not be seen again, we might not even see $40k again!

If you are waiting to time the absolute bottom of the market, good look to you, the bottom
could very well be todays market price!

Or you could wait a other 3 years an take the chance that the bottom of that cycle could
be $45k but in the mean time you missed out on this Bull run.

I invested when the price was about $400 to $600 and there were people who were saying that the price would reach 10 000$, 20 000$ and even more but everyone was calling them crazy but they were true.

Is it now the best time to invest in Bitcoin? It depends on how much profit you expect. It was definitely better to invest when the price was 30K but it's not late or wrong to invest today because bitcoin will reach and surpass its all-time high. From 52K to 70K, you'll see some profit, so it's not late. Btw keep in mind that Bitcoin will definitely reach not only all-time high but will surpass it and reach 100K.

You are correct when you say that bitcoin has come a long way already. Those who have invested during its early times are lucky and have most likely created huge profits already. Despite this, I personally think that bitcoin still has a lot to improve on therefore I know that the bitcoin’s price will increase more. Not only the price will double, but it can even triple.

Bitcoin is volatile and even though a lot of people think that bitcoin’s increase in price is linear, there would be correction phases even during the bull run. The price might go up or go down sometimes and it is all normal. When the price goes down, it is generally a good time to buy and there would still be plenty of time where the price is not constantly going up but also going down. So no, it is not yet too late for others to jump on in the ship.

The key is to know when to buy and always be mindful of your goals.

Some people think about its late to buy bitcoin since it became so expensive compare to its past price. But if you look at the possibilities and current situation where many people talk about something good to come then maybe its good thing to consider about buying bitcoin.

That's why its important for us to consider to learn a lot of things about bitcoin and be updated regarding on the news that recently happen or potentially to come so that we can figure out important things to consider especially upon buying bitcoin without getting discourage on things that we just see.
There's a huge potential for a bull run to come so if you or other people comfortable to buy at current rate then they must do it, but if they are doubting then much better if they listen to their god feel and try to monitor the market so that they can learn something from it.

There is a psychological problem with Bitcoin pricing.

If you look at a share price for example Microsoft, and the price looks very high, lets say 2000 USD per share, then Microsoft can do a share split by 1/10, and suddenly the share price is now only 200 USD, and looks far cheaper than the 2000 USD before. For an invetsor it is still the same to have 1 old share for 2000 USD or 10 new shares for 200 USD each.

Bitcoin has not this option to split look cheaper, so people will always worry if the current price is maybe too high, because of the high numbers

It all depends on your beliefs and what you stand for.

I believe the cryptocurrency sector still has a lot of room for improvement.

If you're looking to invest for gains rather than ideology, I would suggest exploring newer projects with more growth potential.
