lemme know if u ever manage to double it lol.
For a newbie, I would ask them to watch youtube videos and gain knowledge about everything regarding bitcoin. Do signature campaigns and make the little btc you get, collect and trade it at times when you need it. Make sure that you are able to keep track of everything and after a month, take that bitcoin or 1.5 bitcoin and invest it in a cryptocurrency related venture or something else, wouldn't really recommend gambling because of the risk factor. However, if risk is something you're willing to take, try not to gamble the money on online website, that's shit
