Here's the thing, even if you did say "I tried it myself, it's legit", you do know it's all a load of bull in our eyes right? You do realize you look like an idiot right now, right? Who in the bloody hell would believe such a thing, especially by a newly created account? Not to mention you, even well-trusted accounts who would post such things would be scrutinized a lot before a lot of people say it is legit. It's not that we don't believe you, but yes, we actually don't!. We're in the bloody internet, who would believe the word of one person after saying "I tried it myself, it works!"?

Well, to answer the question of legal risks just for the sake of it, there isn't "much" of legality since it's crypto, not yet at least, so it's hard to identify even if there is one or not. Just don't bloody do it if you're worried like that. It's like a killer questioning whether it's right or wrong to kill.
