D – Do not put your money there, ever
I have gathered 10 names here but please feel free to add any exchange you thing it deserves our attention
My grades for the exchanges, along with my reasoning, is below:
Bittrex - C: Recent scare around locked/disabled accounts, lots of recent KYC/security changes, service has also degraded in recent months.
Coinbase/GDAX - A: Licensed and FDIC-insured. I'm comfortable leaving funds here. Free limit orders on GDAX. Not the best trade engine in the world, though.
Kraken - D: Terrible trade engine, does not answer for it and service seems only to degrade more over time.
QuadrigaQC - N/A: not familiar with this exchange.
CoinCorner - N/A: not familiar with this exchange.
Poloniex - C: Long support waits, lots of glitches; I don't keep funds here for long.
CanadianBitcoins - N/A: not familiar with this exchange.
BitFinex - D: Hacked, involved in unregistered securities/derivatives, unlicensed.
BitHumb - D: Seems to be involved in lots of pumping/manipulation, went down for 12 hours at top of BCH pump.
BitStamp - A: One of the most reliable, longstanding exchanges. Licensed. I'm comfortable leaving funds here.
