Why would you even care about them useless coins ? Lol
This comment has come up a number of times.
I fully see the futility for those who never use them... however, they are the "currency" required for use in coin games and they are required for use to upgrade apparel. Love it or hate it, it can be challenging to compete against a coin room specialist without apparel so you may want to invest coins in upgrading your own.
You can buy coins or you can gradually work to build up a bankroll to sustain your play in the coin rooms or wait months or years to gradually build them up by simply leveling up - (you get coin bonuses for each level you reach). There is also a daily spin but it is really insignificant for the most part.
Some members enjoy playing TW's to support their Country Club. Others don't. Either way, they are still required for use. Competitive TW require participation in the higher coin rooms. It takes time to accumulate or win a bigger bankroll to play in the more competitive rooms.
So, let's say you spent 6 months to a year playing lower end coin games to build up a coin bankroll to play higher stakes... you value those coins more than others because you invested time and effort to win them -- as worthless as they are to other people.
You can lose months of work in the lower coin rooms in a single match in Bellagio which is a 2.5M entry fee. The competition is tougher the higher you go...
None of these may be meaningful to you, but I suspect they may be to others that play in the coin rooms.
