I spent my money that I gained in bitcoin in buying my needs and necessity because my only earnings now in bitcoin is too small to buy my dream house and car maybe in the future I will buy those things in bitcoin.
Wow!!! your dream is too high. I think it is achievable if you would invest in bitcoin, trade, learn how the market is rolling and probably buy your own house and car ( which I think would took many months or probably year before you could do that )
I myself, is keeping all that I am earning since I have a day job and I don't think that I need that much money. But last December I was tempted to sell, and buy a few things that I want as a Christmas gift, but I don't do that often, usually just in December.
