I was an antique dealer for 15 or so years.
Was mostly a buyer as my ex was a terrific salesperson.

I saw an incredible change during that time in "buyers premium" at auctions.
A few small houses charged 0% to buyer, making their $$ on sellers commission.
Overwhelming % of houses charged 10% to buyers.
Then shit got stupid. 15%.18%20%....and some big NY shops 25%....ON TOP of charges seller a boatload.

I can see the whole "legal" betting industry following same path. They will not gamble. The will figure out how to lock in profit.
AND, the TAX MAN will be informed about all your wagers/winnings. Nothing good can come of this for the player.
