Dollars getrealpaid is not legit, they don't attend to their client queries and they don't pay as they say... You can get referrals that are required and reach the minimum withdrawal money but they will never release that money!
Crypo is a good market trading but you should be careful with scammers especially who charges alot, Altcoin trading is where you can buy Bitcoin and sell your Bitcoin. I do like it because it's very reactive once you sign in the account it reports on your phone for you to be alert.
