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?
Not that I have come across, in crypto I would definitely not trust anyone with my money because it's so easy to get scammed with no repercussions. I'm sure there are some legitimate places offering signals but a) I don't trust them because many are used to pump coins they already hold and b) even if they are legit it often artificially manipulates the price and it's difficult to profit off this in my experience because buy volume is so low.
