I'm a trader of 25 years. IMO Amfeix is just another Ponzi scheme. Yes, they payout atm. All Ponzi schemes will pay out until they can't.
The way Ponzi schemes work is that most people leave their funds in there wanting more incredible returns. This fact is what supports a Ponzi scheme.
The returns claimed are impossible for even pro traders to attain. Unreal returns are the first red flag.
The second is the lack of review comments. If this scheme has been running since January then where are all the satisfied comments? They only go back as far as May.
The lack of transparency is the next red flag. Legitimate investment funds must provide all information about who runs it, where they are located and how they do it.
All the Bitcoin so-called "investment" schemes have failed. Bitconnect even listed on exchanges to be traded and lasted for years. It worked until it collapsed.
The other ones, Bitpetite and the other recent one (can't remember its name) were scams. If the return is too good to be true it probably isn't real.
You might not think 0.1 BTC as a min investment is much but that's over $1,000 atm. If you get even one thousand people to pitch in that's a million dollars.
This scheme will collapse just like the others. Having said that, if you get in early on any Ponzi scheme you can make money if you withdraw your profits.
Letting everything ride forever guarantees that you will be taken in the end. If you can get your money back, withdraw it then you can let the rest ride.
This way you haven't lost your money. It's just that human greed takes over most people's minds. They WANT TO believe it's true and ignore all the red flags.
Conclusion: If you have a thousand bucks to lose then go for it. When/if you get your money back, withdraw your initial investment and then you've got nothing to lose.

Vice Token is a huge red flag. It's a convoluted process to buy tokens that aren't even tokens and I can't even work out if it's an ICO. When I went to Telegram and asked some questions they kept referring me to their rules that stated I wasn't allowed to ask about that. I wanted to know if the tokens would be tradable off the Vice exchange and they kept telling me I wasn't allowed to ask that question. They eventually replied that they wouldn't speculate on that. So if they consider that speculation then I'd say the answer is no. I pushed the point and they banned me within minutes. I don't like the whole process so I'll be staying away.
