Etoro.com is also unavailable in US, but they still have more than 20k users trading BTC there and a market cap well north of $100m
The 20k users trading BTC on Etoro.com are NOT from the United States.
Where did you get that $100m market cap figure?Last time I checked eToro was a private company, not publicly traded.
I guess he pulled that $100m market cap figure from his ass.
