If yes, What need you reinvest your money on Bitcoin?
Please rearrange your words, what you mean by 'need'?
The question is confusing, I think what he/she wanted to say is "If yes, Why you need to reinvest your money on Bitcoin".
And if that will be the question. My answer would be; Yes, because I already learned the potential of Bitcoin now, lesson learned if I sold my Bitcoin at loss before and I have knowledge now about Bitcoin. Because what I believe is, if you ever bought at the high price, then if you sold it lower to your buying price, that time you will lose your money.
Just like you I also do the same,but whenever I loss some money I stay on being positive because no matter what we do we can or we will always experience it. I also analyze what went wrong and learn from my previous mistakes. It also depends on how you handle your own investment.
