With "saving wallets" where you deposit and gain interest over time. (5% interest per month at launch!.
Well, obviously it is some type of ponzi or scam.
Maybe you are just dumb and you think that you can give people 5% a month. But you can't. The risks are enormous, and even if you don't plan to do this, you will end up running away with other people' money.
I advice everyone to stay away from you and your projects and ideas.
Any tips then to gain user trust?
Being trustful, what ofc you are not.
You should study and understand the risks of what you are doing before asking for other people's money.
