To assert that 1.5% yield a day is unsustainable is a bit strong in my opinion. A properly tuned trading bot can yield significantly higher than whatever you can even imagine. From the information I have gathered 1.5% daily to some people in this cryptocurrency world is nothing. Some can see %50 returns. Leave the old ways of thinking behind. If you are too scared to play go beg the banks for .5 a year and see if thats not a scam too. Have courage to lose. CF is subject to exchange b.s like everyone else.
They need to invest in a coin and blockchain.
I'm not scared of losing but I don't invest in scams. The hard truth is that CF is a scam, just like Crypto Solutions and many other. Every multi level marketing and HYIP is a scam. If you like loosing money, send them to me, at least I will be thankful :)
I'm not a guy that thinks behind, just because of crypto I have almost 7 figures in assets, I was also able to make money on stocks but nothing beats crypto. But HYIP are old technique of scamming people, I would never invest a penny on them. Think about that, would you pay 150$ every single day for the rest of your life if somebody gave you once 10,000$, nope.
