For each month of holding add 5% - this is a good profit. Are you sure of success in advance? What will provide such large payments?
Exactly, we have already seen projects which offered crazy % amounts per month and ended up very bad.
I don't mention the names of these projects on purpose to not start a stupid discussion and to avoid to compare them because it is irrelevant.
The most important question is: from where the team will get all these tokens to be able to pay such high monthly rates?
Or is this only an advertising and these rates will be changed just after the start of the bonus round? Like in many projects before also.
