It's legal and I already betmax it in my country and few others. I am not sure, as I said it's risk I am willing to take.
There are plenty scammers but only idiots would take 200e and disappear when they can have more than that almost everyday without any risk
I think it's a pretty basic thing that it would be hard to do that because if you let someone else play, how sure are you that you're going to get your money? (meaning you win in the bet). I still yet to know why you are interested in doing that. Probably illegal in your place?
PS. Not interested with this
