Experts, i want to know how to sell token from my ether wallet. i have many tokens about $100 but i can't sell those. what is the gas limit ? please help.
Unfortunately, there is no general answer to your question. Whether the tokens are transferrable depends on what tokens you've got. It would help if you specify which tokens you want to sell. Then you might check
https://coinmarketcap.com/, serach for oyur token and then click on 'Markets'. It'll show you where the token can be traded.
The gas limit isn't that important either, far more important is the gas price (gwei).
