hi
when launching a new ico on erc20
what is the first step when looking at exchange listing?
First of all before launching the token the team must have a clear goal and a roadmap with plan that is not longshot. People will be willing to invest in an ICO only if they are having some already developed model (a beta software for example). Also proper marketing on social media is imporant. An exchange will be willing to list it if the market capitalization is more than 1000USD in general.
Again being listed on those exchanges which have high trading volume allows large buy/sell orders thus making the coin more popular and get a higher rank on coinmarketcap
what is the most accepting exchange ?
What do you mean by an "accepting" exchange? an exchange that accepts every shitcoin? Then I suggest Yobit and listing it there only will put a red flag on your project. You would definitely want one of the top exchanges to list your coin like Bittrex, Poloniex, HitBTC and others.
