Their free depositers freeroll is very nice, not many players on it, most of them disconected, so it gets easy to get on prizes. The other tournaments have just the right ammount of players o guarantee good prizes, but not to be forced to play them for so long. So I love the tournaments there.
As for cash tables, not to many players, but a decent ammount, you can even multitalbe a bit if you want (2-3 max, depending on the stakes).
Their recent software improvement was good to, so yes, betcoin.ag!
you can multitable more than 2-3 tables i've had up to 10 going....
Like I said it probably depends on the stakes and time of day. For now I was only able to do it at 3 max, and I could not even play at the same stakes. But I don't multitable a lot, so its not an issue for me.
