For those looking for an alternative to coinbase to buy and sell bitcoin and ethereum with USD at the best prices and also with low fees check out Gemini.com
My state of Washington was just added and I signed up 2 days ago. It seems the verification process is back logged and could take 2 weeks they say but I'm seeing that it will be well worth the wait.
All 50 states are supported except Alaska, Arizona, Hawaii, Oregon and Wisconsin are coming soon.
Click here for all supported areas.
An example of the difference for one bitcoin right now on coinbase with fees is $2,774 and on Gemini it is $2,714 for a $60 difference. The fee on coinbase was $40.73 and on Gemini was $6.77.
It looks like their trading fee is .25% so that is low too.
What I also like is you can limit buy and sell. So no more just buying and selling at market with coinbase. (Well once I get verified)
