Hi, is there any way to get alerted when certain tokens gets released on the market after an ico?
I have never tried, but you could monitor
https://coinmarketcap.com. If you click on a coin, you will see the markets where it is traded. I don't know if they update the list on a daily base, though.
When a coin get's on an exchange it's not updated on coinmarketcap at the same time, so coinmarketcap can be good to see the exchanges where a coin is traded. But not to know the exact time a new coin is listed on an exchange.
