Hi @doitvoluntarily!
Like most of us, I have used many different exchanges over the last 3 years.
My faves are: Binance and Bittrex.
The rest, I have had hit or miss experiences with.
I’ve most recently used Coinfield (a Canadian regulated exchange) however they still seem under-prepared to move large volumes of coin. I use them really only to trade fiat directly for crypto, in smaller increments (less than 10,000).
