I have joined some HYIPs in the past and of course, I invested money too to earn more. Unfortunately, before I could cash out the website crashed and turned to scam after so I haven't got any profit from them. Joining HYIPs are very risky. You also need to know the right timing and much better just only join once and get the profit, and if possible invest it again. If it goes down the drain again the only thing you lose is your time. If it were me, I'd rather bet on a
casino game because I know it is risky and I know there is a high possibility that I won't win than joining HYIPs, expecting to profit but getting scammed in the end.
