I forgotten a site where I've invested only 1mbtc and got 8mbtc. If anyone knows about it please let me know. also similar sites like that will do. Thanks for reading.
i think is very dificult is legit site invest can give return 8x in capital money
if you play gambling much site can return 8x
this hyip majority only return 30 - 100% every month if can return 8x maybe only several day scam
