Bittrex is the kind and most trusted site from where you can buy ERC20 tokens. Etherdelta is very complex for a beginner. So bittrex, hitbtc or cryptopia can be best choice for you to purchase ERC20 tokens.
Are you sure, because i am really confused with these Bittrex and hitbts.Which one is more usable to beginners?Can anyone help me to solve the confusion?
