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.
No one is against the idea of selling though but in this thread, we are focused on suitable ways to accumulate Bitcoin so that we can hit our targets. If you are comfortable with what you are holding and the price you want to sell, then you can sell.
In the meantime, I want to go against what you said about too much accumulation. There is nothing like too much accumulation if you have invested more than your target there is nothing wrong with that. Some people go as far as setting another investment goal after reaching the first one because the more profitable you will become if you have enough Bitcoin in your portfolio when the time for withdrawal has reached. Unless an investor wants to diversify into another asset there is nothing wrong if he keeps accumulating Bitcoin when he is not ready to sell yet.
