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".
I think so that's what he wants to ask and I'll give my answer too.
Reinvesting is already part of my life and I have never been serious like this in bitcoin. Before knowing bitcoin, I'm not open to any investments and ventures and knowing more about them.
But after knowing bitcoin and learning what's potential of it, this made me serious and made me to want more of it.
