Is wholesaling legit, legal or worth the time?

[John C.]

So I have been watching a bunch of videos and reading things on wholesaling after just finding out about it the other day.  From my understanding it requires a lot of work and can be harder than youtubers make it sound but it can pay pretty well and is legal. You can learn how to do it all by reading online and watching youtube and just doing it.

 After looking at a realtor forum though they seem to have a very negative view saying that it is basically a scam for people selling “courses”, and that it is very close to at times or is illegal.  They also say it’s basically impossible to make money for 99% of people.

Which is it?  I would hate to put tons of time, effort and maybe money into it if I would just be better off trying to learn to code or something with that time and effort.  I also don’t want to get arrested or anything either obviously. Would i need to get a lawyer to check my contracts before using them?
