I know the title may sound a bit odd, I didnt really know how to word it.
Anyway, is there much (if any) for legitimate services that will sell people trading advice (like buy this coin now) or that will have you deposit your money and have them trade it (similar to investment firms that we all know) in the crypto world?
There are plenty, but most of them suck, and will lose you money (on top of the membership fees). You're better off curating a good feed on #CryptoTwitter, lots of solid, free advice and charts going around.
The only good "copy trader" service is on 1broker, but they no longer have a BTCUSD market. Only forex/stocks and stuff like that.
