Bitcoin is still not that stable compared to gold, and it is going to take a while before the price stabilizes,
the reason is the small number of bitcoin users and transactions.
It is not yet at the level in which it can be trusted as a stable currency, which favors those who are into trading, as the price can swing wildly in a matter of days.
Yeah a lot of winners now in the trading industry in this currency. Just a little swing can make all the difference for they got a large number of bitcoin in their hands. If you will include altcoin then they can manage to get $100 dollars a day.
That unstable price of bitcoin also give one chance to get so many profits from trading activities. I agree with you about can take 100 dollars profit every one day but it should have big capital too.
Even few days ago my friend trade and hold bitcoin around 14 more
BTC after the price growing up highly he got more than 1000 dollars profit in a day . I wonder it.
