I'm looking for companies created to solve the issue of adoption that is currently facing bitcoin. Payment processors like GoCoin and Bitpay are looking to solve these problems.
I think there is a big market here. Bitcoin is becoming popular with merchants because of the low transaction cost and non-existent charge backs.
I've only found one stock (BTCS) for something related to this, but it looks like they already got pumped earlier this year. They did just hook up with GoCoin, so I'm going to continue to keep an eye on them but I'm definitely not ready to get in.
