Hello there I just wanted to know best site where I can exchange my bitcoins to ether and ether to bitcoin quickly with the lowest fees.
you can try
https://shapeshift.io/#/coinsthey offer competetive rates and their exchange is legit and very fast
not sure about the LOWEST fees but it is well worth a test
He already mentioned shapeshift already and used them but did not like them due to their high rate.
This is from it being instant.
