If my erc20 tokens gets a value, How can i convert my erc20 token to ETH?
First you need some gas for you to be able to move your tokens from your mew wallet to some exchanges that supports your tokens.You can go to coinmarketcap and research which exchange supports your tokens for trading,if you have already a good exchange for example IDEX,you need to put your tokens to IDEX's wallet but you need to have a gas in your mew or else your transaction wont proceed,thats very easy.
