Bitcoin price prediction always seems like an easy way to make money, as predicting is very easy, but it hurts to say that for all the multiple times I've tried, never have I been lucky enough to win it, and I am assuming this is due to the current high volatility of the price of bitcoin, for several weeks now, price hasn't been that stable, so price prediction in such a market condition is pretty difficult to win from..
You are the first person whom I have heard saying predicting bitcoin price is easy.
Everyone else says that predicting crypto prices is a difficult job and it is indeed.
The price can change by a huge margin in just one day. It becomes difficult to tell what's gonna be the price after 8-10 days.
I would say that predicting the BTC price by placing bets on freebitcoin is a deceptively easy way to make money. In fact, as you already said, BTC can be very volatile, and sometimes it really can only take one day for the price to leave the range you initially expected and placed a bet on. Probably, now only the FUN token is more or less a safe betting option on the freebitcoin site because this token is not very volatile.
