It's already a huge profit, so you could sell your bitcoin already it doesn't matter since you could always reinvest that money when the price of bitcoin dump in the future or when the bull run ends. It's difficult for a lot of investors to sell at the peak of the bull run of the bitcoin and only a few percent of investors actually do that. Maybe selling by portion could be a good thing maybe 15% every time the market price continues to pump also so could always earn a profit because you already made a good profit by holding for a long time actually. You could hold for a bit just decide on an exit strategy because for sure there will be a dump for sure or else plan to sell it on a higher price value around 200k$.

all humans are not immune from the mistakes they make, so it is not true that they don't need advice. just a suggestion is fine even though later it is himself who will decide whether to do it or not.

Your suggestion to observe the movements carefully is the right thing and needs to be done, because it could be that the decline continues not to be hindered, so you can take actions to stem so that there is no loss that becomes even greater.

but seeing the trend of bitcoin so far, there shouldn't be excessive fear, because bitcoin has always been doing this from last year. bitcoin will continue to increase until the end of the year. If you get bitcoin results from 2018 you should let some of it go because you have made a big profit and don't be too greedy because it could be detrimental.

Depends, what is your goal? $60k ? $100k? or maybe $1million.

Always set your own target, so you will not lose ur opportunity to sell.

When i decided to invest on something, i always set my own target so even the price rise after i sell i will not regret it.

I agree with your strategy, I also implement things like that. do it when you get profit and buy when it goes down. This kind of thing is classic but minimizes the risk of loss, so instead of holding long term but getting a price trap it's better short term but running all the time

Its your choice but most of the forum members might tell you to hold, but make you should base your decisions with proper understanding of the market. Make you sure that you will decide with confidence and will not blame yourself or others for a bad outcome your decision but as long as you already made profit your good.

You have made good profit in your btc so there is nothing wrong if you decided to sell now, but it would have been better if you can keep maybe %40 and sell the rest, if btc will still hit the $100k target I don't think you want to miss out.

No one can provide an accurate answer with your question, it's your money, your investment right? deciding to keep holding
or to sell will rely with your deeper understanding.

Knowing the timing and acquiring experienced from time to time will guide you, everything around this sphere needs an approriate
decision making, take time understand for the betterment of your long term engagement to this market.

i am crypto optimist and believe (as many analysis show and most people predict) BTC will grow in 6-digit price later this year or in the beginning of 2022 and will probably (most likely be) anywhere between 200-500K in the next cycle.
however i am not greedy and know very well that there is a realistic percentage (1-2-5% who know) that things turn in the wrong direction. i mean no interest in bitcoin, many goverments ban etc. in this case it will be worth nothing and you will have something with no value. you will have nothing while some months or years ago you have had a fortune. so i decided back in 2017 during past ATH that I would hold my coins and sell it all when price hits 100 K or close to this level. that's my limit. later on if price follows past halvings patterns I will buy back at dip approximately same amount of BTC i have now. I appreciate all your optimism and truly share it...however keep in mind nothing in life is sure and eternal. so don't let the greed spoil your life and future and please put yourself a personal limit.

It depends on the goal of the traders whether if its long term or short term. But you are right about your statement above. You can't have profit unless you convert or take your profit in BTC. This is the common mistake of traders, They are becoming greedy when price is rising then FOMO when they sold which is the reason why most of traders never sold in profit.

Congrats for buying bitcoin at such cheap rate. If I were you I would have sold all my bitcoin at 60k and wait for return of bearish market. Bitcoin can make wild swings in all directions, its better to quit if you are getting huge profits.
