Was about to make a deposit with BTC into Pinnacle with their Cryptopay method. The rate they give for BTC deposits at this moment is $5065.72/BTC. The current price in my Blockchain wallet is around $5250/BTC. That's around 3.5% to deposit, which is very disappointing for a book like Pinnacle.
Also received a withdrawal a few weeks back. The rate they payed out was about 2% less than the average price of BTC at the moment the transaction was sent.
So Cryptopay charges anywhere between 2-3.5% on both deposits and withdrawals. I don't even know if it's worth it to play there anymore if funding with BTC.
