Maybe I'm one of those people who is holding on to the slimmest of hope that something can be worked out, but why couldn't a book do something like this:
1) Cover your Betislands balance provided that you match it
2) Give the account a 20x rollover
3) Impose the following limits
NFL: $500
CFB: $300
NBA: $300
CBB: $200
MLB: $200
You will not attract the big balances (many of them sharper players) because these terms will not work for them. Believe me, I feel worse for the people who lost life changing money than I do for myself, but I'm just trying to be realistic, and looking at this from a book's perspective.
Say a player had 3K, if a book allowed this, they match it and are into the player for 3K to start off. If a player is betting into -110 lines, and has to make $120,000 worth of wagers, the book is.....
Up $3,000 provided the player hits 50%
Up $1,580 provided the player hits 51%
A player would need to hit 51.4% to break even, or the same as dealing a -106 line if they didn't have any kind of bonus.
They'd gain some good will, good publicity, and new clients. This doesn't seem that unreasonable.
