No way I'm going to even understand why this dark marketplace for stake accounts is that big, nor why would anyone who has been wagering hundreds of thousands would sell his account for that cheap or who would pay hundreds to get a few tens of $ each month in bonuses.
Anyhow, people should be grateful for the tiny bonuses they get over at stake, I'm having a really bad month over at betfair and the only thing I got were 5 odds boosts and one free $5 bet, which I don't want to talk on who I placed

Also, it may be possible that people might be selling any hacked accounts if not their personal ones. Obviously no one should sell his high wagering account. Even if someone want to leave gambling forever and want to take a break from gambling, still selling the account is not ethical.
I would suggest everyone to stay away from these dark marketplace for buying the stake accounts. I am sure most of them who tried to buy would be scammed in one way or the other.
For those who make big wagers and achieve big VIP levels, gambling is not an emotion, it is their attitude. So I don't think anyone will ever sell their attitude. If such an account is available for purchase somewhere, it can undoubtedly be a hacking account. Or someone can scam with a tempting offer of such an account. If gambling is a form of entertainment for you, then you will never decide to buy such an account. And if you have greed and want to get something big from the U R platform, then only because of that greed you may be interested in buying such an account. Buying such an account would never be commendable.
In fact account sales was massive few years back when the bonuses in Stake still can be considered as big although the account did not wager much.
I know some users wanted to sell their own account because they want to stop gambling so they offered the account, it is logical thinking ofc because they can get some money which is better than they just stop gambling and let the account dead lol.
Means that it is possible for those users who have wagered a lot to sell their own account because of a reason, but of course it will be risky for the buyer because high possibility the account will be banned later because account sales is prohibited in Stake and in almost all casinos.
