Learned about Gemini here at SBR. Got killed for 3% on my last two bitcoin transfers using Coinbase.
Gemini charges 0.15% so the cost was $1.50 to buy and transfer $1,000 to Bovada which I just completed. Football season transfers to Bovada ran about 2.2% using Circle and Coinbase.
It is a two-step process to buy and transfer which takes a little bit more time if you have used the automatic buy and transfer with Circle and Coinbase.
I don't believe the card option people prefer is available but it is dirt cheap for bitcoining.
Highly recommended. Goodbye Coinbase.
