I got sidetracked by my employer last night and today... I will check with Korea and the Asian market.. I know a big news came out of RobinHood and brought it up.. It is a cloud-trading platform (hint hint since you know my background and they are going into the crypto with their app... Insight of RobinHood - https://aws.amazon.com/solutions/case-studies/robinhood/ - US customers only since it needs to be validate who you are .. They are low or free transaction fee.. I use it for my stock purchases.. Also, use a referral if you are a new customer and you get a free share).... I know the crypto part is in there but cryto trading is not available yet it seems... I like Robinhood)...

This could actually compete with Coinbase for ease of use buying and selling of crypto...
