LOL, a 10 btc coin and your asking 30BTC..
anyone who buys these any pays your prices are insane or not thinking about the future..
when bitcoin is worth 100K each, and your holding this 10 btc coin worth a cool million it will feel good i assume.... BUT how in the world are you going to get $2 million premium when you want to sell it..
Its never going to happen!
Good luck though!
