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 the strategy you asking for is exist so there will be many people being rich already. Just gamble it on games that you like and test your luck, nothing else. But I recommend you to do sportsbetting or poker.
