If this is in line with trading, I don't think we can make this ROI safely as several unforeseen circumstances can happen and risk is always going to be there..

But for some kind of consistent profits, staking can be considered as an option, another option is getting into business with some  gambling platforms that can equally pay you a decent Return on capital for providing liquidity to them and pay you a returner..also let's not forget very few will give high ROI as they too are in business to make money .
