Aha, I guess this is why my coinbase account was closed today. I didn't even know what I do with my bitcoins purchases got anything to do with them. Wow, Durex threatens to stop selling me condoms too if I continue laying random single one night stands.
I have dozens of transactions to and fro a variety of gambling sites each day, didn't even expect a coin seller to meddle into what I do with coins i bought. No emails, no warnings, just sudden closure.
I'm disappointed by coinbase's decisions and actions but hey, it's their lost not mine. I hope they maintain this dumb rule, many other sites are doing what they do, buying and selling btc, many more are trying to compete for a market share in this area. They'll get squeezed out of business when another capable btc trader comes along....I hope to see it happening soon:)
