Nah, this is simply to good to be true, there must be either some kind of wagering involved or this is a scam.
If it's too good to be true, then it probably is a scam. 75% commission is very big that too lifetime, sounds suspicious. If they are giving 75% of the affiliate balance without any restriction then, how they are going to cover the loses. If I am making one alt account using my affiliate link, and depositing 1 btc. I would get 0.75 in my other account. Great deal lol
