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.
Since you're posting on here, in other words you want to ask about betting strategy, aren't u? My advice just betting on sport with martingale strategy (when you lost 1mBtc, you double it ( 2 mBTC) in next bet, when you lost, bet with base bet (1mBTC).
