Actually this is my reply to a question asked in altcoin section.
I thought it would be helpful to most of the newbies who are doing bounties
So i post it here.
Decentralized exchanges let you trade most of the coins(tokens).
IF the token is listed in a decentralized exchange use following sites.1. IDEX -
https://idex.market/2. Etherdelta -
https://etherdelta.com/Using Etherdelta is not advised because of it had lot of security issues and down times in recent history.
Instead use forkdelta. Actually it is forked from etherdelta.
3. Forkdelta -
https://forkdelta.github.io/In some cases, some tokens are not in any exchange including decentralized ones. (Ex: Pindex-PDI is not yet in any exchange sadly)
Then we can use the smart contract of the token to trade. This method is very useful to buy some tokens very cheaply before they come to the market.
The procedure - How to trade any token using the smart contract address1. Go to Ethplorer.io
2. Search the token you want to trade in search bar.
3. Get the smart contract address of it. (Contract address)
4. Go to the url -
https://forkdelta.github.io/#!/trade/
-ETH
5. Refresh page again.
6. Now you will find the order book. Place sell order or sell to a order already there. If you want to buy place a buy order.
Happy trading!
