You mean this is some kind of investment management platform? Is this kind of business even popular out there besides the ones scammers usually offer? No sane person would take on this risky management deal.
The thing users hate most is the lack of human support.
I have not seen this kind of service before, but scammers can respond to people very fast. Investment scam is very common.
Realistically, as long as Bitcoin is concerned you can hold it for long time without you having to launched any other investments platforms as many people could actually think is a Ponzi scheme platform without them knowing that you are genuine of what you are doing.
There are even enough exchanges now, but self custody is very important. 99.99% of investment services that I have seen before are scam. They can easily be known.
Ponzi scheme is still very common this days.
