How to grow the bitcoin you have without being involved in gambling or putting it in a custody wallet for APY. Is there any proven low risk method.
The only other way that comes to my mind, is to trade. You can try to find some arbitrage between some exchanges if you don't like to gamble or make some Basis trading aka Cash and Carry trading between spot market price and futures price. But if you are cautious and adopt a defensive strategy, you could make some profits by trading in a classic way at the moment without big risks.
