Just wondering, who is accumulating Bitcoin via using it as a method of being paid, so instead of being paid in dollars or any other amount you ask client to pay you via Bitcoin especially merchants and freelancers. I think it is cool to be paid via Bitcoin because it appreciates so its like you can earn twice if you sell high.
It is a good idea to use bitcoin in online shop as their payment method to have an easy transaction. It is helpful specially to those who don't have credit cards because it is easily to reload your wallet using bitcoin.
