It's not just all about buying bitcoins and accumulating them,also know when to sell,Because too much accumulation,will not end well for you and you might as well miss out the opportunity of bull market.
How can you achieve this,it's very simple all you have to do is to stay informed on the market trends.
You are just a misinformed trader. You can say whatever you want, but I advise you to at least DYOR before saying accumulating much BTC and not selling in the nearest bull market does not end well. There are people who accumulated bitcoin in 2018 when the price was slightly above $3k and continued accumulating then without selling, what do you say about them?
Their investment of 2018 alone has met a whooping 33x as at $105k, which other business would they do and it would give them such gains? would you convince me that such a person who has not sold since then that his investment is not ending well for them now even if their holding target was 7 years and they decide to sell now? of course even if such persons decides to hold longer and has a target of 10 - 20 years, then he has more profits to enjoy and whenever his holding period ends, his investment ended very well for him.
Perhaps you lack information about the profitability of bitcoin investment and the compounding effect bitcoin price appreciation has on holding for a longer period as compared to succumbing to short-term gains as you are describing.
