Me and guys from cryptocurrency trading free Discord group https://discord.gg/8BYTCg2 (click to join) verify bitcoin exchanges that need no documents and all time.
The list of anonymous cryptocurrency (ethereum, litecoin, neo, eos, bitcoin etc) exchanges is on - https://fuk.io/no-kyc-exchanges-list/
Lately we had to remove:
- Cobinhood exchange as it ended as exit scam
- cryptopia exchange as it is dead and in liquidation
- hitbtc due to loads of coins not withdrawing and markets down
- Wex/BTC-E was there too but its so dead, not even worth to mention.
We are going to add a few exchanges in coming days ie BitMax (yes, this is unique info for Steemit readers) and... that we wont say ;) But some hints are in ebook - http://cryptoincomeguide.com/
