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.
