I avoid investing in projects that promise returns above 10% per month. I believe that this is the limit of the real possibility of profitability.
They simply attract inexperienced investors to their projects in this way, and then in the future simply close it, money is raised for their own purposes.
That's not the limit. This is a certain stable figure, which can be done even by ordinary people, for example, in the trading of crypto-currencies. 10% per month is a stable profit. If we talk about Crest tokens, they chose the optimal price of 10%, which can bring investors a constant income. This is the optimal percentage.
