AS the topic says, how can one make some good amount with 30mBTC ( 0.03BTC)? Please just don't say gamble, try to provide some strategy. This topic can help others who want to make big with a small start.
if that is all you have then do not gamble with it because gambling is risky and you may as well lose it. what i want to say is that you should
gamble with what you can afford to loseand after you set that amount in your mind then you can start gambling, you can choose a simple game of dice with martingale method and start from small bets like 10 satoshi and be moderately safe and make some profit.
