Funny that a lot of tax advice regarding crypto I have found is on steemit and bitcointalk. Not to say I fully follow those advice but crypto is so brand new that a typical tax accountant usually has no idea how to deal with cryptos. I hope this changes very soon. US is terrible now because the country just revised crypto investing that can not be deductible in 2018. That means every trade made if its a profit the profit will get taxed. Rough start to the new year for US crypto investors.
