I've been burned several times day-trading, also made quite a lot of btc but most of that was down to luck and the right timing. Managed to turn $200 into $8000 just by investing in DRK when it was selling for 200 satoshis.
it is true if it is very difficult to predict the rise and fall of the coin, this is very different from Forex, I think only luck that can make you a good profit.myself have lose a lot of btc because of trading
