There are some terms which you have used which am not too comfortable with as an investor. When you say never sell Bitcoin because someone is greedy for money I begin to wonder what exactly you by that. So let me ask you this question what is the reason why you have Bitcoin is it for decoration? The primary purpose for every investment is for profit maximization and you know it. I will take profit in my Bitcoin holding when I see a certain level of profit that am satisfied with. I will continue buying again after taking the profit buy using the same strategy I used in accumulating. That I sold my Bitcoin when I saw a good profit doesn't stop me from holding Bitcoin again.
