That would require a massive amount of wins, or at least really huge bets in the really good moment, for example we could see something like that at betking, where someone has won over 200 bitcoin with a single win!
Unfortunately, moneypot.com has faced consequences of losing big part of their bankroll, the investors have got a really huge loss from the money invested.
So as even newbie can see, every kind of BTC investment is risky, you should choose the one with the best rate of profit, taking risk under consideration.
