There is no way where you can make sure sort money. Atleast in the crypto field. Yes you can try staking the cryptos in popular exchanges like Binance and they can give you small interest in return. But I think that won’t be sufficient for long go. You can buy coins and hold them for long term if you want, this won’t give quick and huge profits, but will give sufficient ones. I don’t recommend risking money at high stake for steady returns. Moreover if possible copy trade any big trader, definitely you can make good profit from it.
