I understand crypto is world wide, but I would expect at least 30-40% investors from US. I would love to hear what others do currently or plan to do during their 2017 filing in US.
It's closer to around 17% based on source IP addresses to the top 10 exchanges (not reliable due to VPNs, but the best indication). I'm in the fun position of being both in the US tax system and a UK citizen- so before I moved I sold my crypto assets to a UK Limited Company, and they'll have to file in the UK for corporation tax on liquidation as they would with any other intangible asset.
