It depends on the feature of the token obviously.
If it just a playmoney to play the game without any other features then for sure it wont attract players.
But if the token is something that has some attractive features or function such as:
- The one on Bitsler, where players can use it to participate on contest to win real money.
- The one on Chips and some other sites, where player get the token by wagering then player can stake it on the vault to get some earning.
- Exchangeable token where players are able to convert it into real money.
Those features will attract players as players has the chance to earn or win something from the token.
I cant agree obviously, if those are not giving any benefits to the casinos then why those Casinos keep it for a long time?
If it does not give any benefits to the casinos, they have removed it already.
That's one of the marketing/promotional tools for the casino, casinos needs to offer something for players to make them stay as long as possible.
Coming up to avoid abuse, casino that is managed by professional owner wont be so worry about multiple accounts as they knows how to deal with it or how to avoid it.
Casino owners who knows how to managed the business are capable of bringing something that make sure that the house are not being abused, even there are lots of attempts coming from those abusers.
This business is a long-term and stable, professionals who managed to build reputations and to have a good communication with their active players knows how to deal with any kind of abused.
They've got the system where they can check what are the possibilities if ever they'll offer something generously, it's part of advertisement and it been assess before they'll offer something to keep those gamblers enjoying their platforms.
