Hey, I am back.
Sry about that I did not mention about the duration. The 20% is for annualized return.
And do not judge that it must be ponzi scam please, because if something is a ponzi scam, then it would never set a limit of selling the fund.
BTW, nothing is impossible. For example, you can check the quarterly contract of Bitcoin futures in OKEx and Huobi Global, comparing with the real-time bitcoin price index, its price index has a price spread. That is a thing if you have a good quantitative trading strategy, then you would be able to arbitrage from the market.
That is how the quantitative fund works.
You say noting is impossible but when it comes to getting profits in the markets and still guaranteeing the capital of whoever invests with you we can clearly tell that is indeed impossible, anyone that knows anything about the markets knows that you cannot win 100% of the time, there are many periods of time in which the markets do not cooperate and instead of desperately look at them the best option is to do nothing or you will overtrade and lose money that way, so what you are proposing is simply impossible and there are only two conclusions we can reach, you either have a flawed understanding of the markets or you are being dishonest about your offer.
