You are right, there are enough swindlers, thanks to them, Bitcoin fell at the end of 2017. You can do nothing and not be afraid to get a swindler, but than you can’t earn anything. I’m ready to take risks. There is still quite a bit left and I will return the amount I have invested by percents. And I get a profit on the referral system too. So I will not lose anything 100% and earn money for sure.
