this is difficult...
I have tried mining, buying shares, reselling bitcoins, etc but nothing had given me a real benefit (if in the meantime, the bitcoin price's goes up, you'd probably lose because dividends in dollars keep the same, but in bitcoin is lower, so you will have less than your first bitcoin)
you could try trading in an exchange, but you have to read a lot about stock markets if you don't want to lose
so, u try trading in an exchange. u profit for that?
if yes, can share u strategy to trading btc. thanks.
