Guess I have been lucky. I sent a couple deposits to a few books and havent had Coinbase shut me down yet.
They are a pain in the balls though. Circle is much better. I also got bought some instant (when price tanked a few weeks ago) from trucoin, but they charge 60 bux per 1000 and you can only buy 1000 worth per day. Plus they add a premium on top of it. I think I paid 221 or 223 there and they were 217 or 218 at most other places. Theyre listed at 245 right now and theyre 237 on most exchanges. But thats the price of expediency I suppose.
Bitcoins a lot like books though you need to have funds (cash) available all over the place to hit the spots where theyre too cheap to not get a few.
