I want to use ETh on coinbase Heeelp!!!!
Since you mentioned that you want to used your ETH on Coinbase then let's forget your LTC at Binance. And you also want to do it on Cryptopia as you mentioned.
-Head to your Cryptopia account and go to deposit page. Look for ETH and grab your ETH deposit address.
-Head to Coinbase withdrawal page and choose ETH then send it to your ETH deposit address on Cryptopia.
-Wait for your ETH to be reflected on Cryptopia (sometimes takes few hours and
sometimes it will dissappear with no trace lol just kidding)
After your ETH was being successfully reflected on Crytopia , trade that to BTC since no available market for ONION/ETH. After that, head to ONION/BTC then do the usual trade.
In the past, there is a direct market of LTC/Onion on Crpytopia but now it was closed so you really need to trade your ETH to BTC first if you preferred using Cryptopia.
As mentioned above, Kucoin has a trading pair of ONION/ETH so you might want to consider that.
