I have deposited and am enjoying the .5/.10 stakes.
Not sure why they are getting hate. I think it's a great poker room with good software. Way better than global poker mainly because it has way more players.
From what I've seen, I don't think it's hate. It's caution.
It's new and the concern I'm seeing on social media has to do with taxes through sweepstakes. Because different states in the US deal with taxes from sweepstakes a different way. Some are worried that taxes (normally when you make above $600 or so, depending on the time) are deducted straight from your winnings without regard to possible losses. Say, you deposited $1000, and lost that $1000. Then you deposited another $1000 and won $1000. Even though you would now be even, you may still be taxed on your winnings of $1000, without considering your losses.
There have been some debate over this on social media, while ClubWPTGold hasn't given a clear answer, because they said they cannot give tax advice and to consult a tax professional about that, because every state is different. There are some states that you can still treat wins/losses as a whole for the year for tax purposes, even as it's listed as a sweepstakes.
As for the games, personally, I'm enjoying them. I only play the MTTs though. Won a few tickets, but haven't cashed anything yet. And I've only played the low buy-in MTTs using the daily SCs I get. The play is very soft at that level right now.
