Here in the US, I have found that the lease expensive way for me to buy ADA is to get ETH on GDAX for no fee and then transfer the ETH to Binance and buy the ADA there and then send that to my wallet.
I am wondering what is the least expensive way of converting ADA to USD? Is it just going the opposite? Transfer ADA back in to Binance and then convert to ETH and then move that to GDAX?
Any tips would be great. Thank you!
