actually there's no invest site in the beginning,they all are a scammer,
all of them make a promise that you will get 1~10% each day,and after a few days they gone,
that's their strategy to make a money from our greed and obviously people who's trying to make a money will tempted by it,
no matter what,if they promise you to get % from your capital /day or /month,
if they survive more than 1 month,more likely they're doing a pyramid scheme,
they survived because of costumer money,and they will make it as a % of your capital as an earning from others people money,
so stop bothering with this kind of services because it's totally scam
Actually there are so many investment sites which is really promising and of course a legit too, but OP is talking about ponzi sites and you're talking to almost investment sites are scam as you say in bold letters. And of course I'm talking here to some ICO sites which is clasified as one of legit investment sites.
And to OP thanks for your effort to do this but all ponzi investment site are scam so you dont need to list them because they will popping up every day with different names but the same website designs. But in the end people are still going go to this kind of sites which is really stupid.
