    Hello all, I am going to gather data about crypto exchanges (i.e., binance, bitfinex, ...) specifically regarding when they listed the cryptos (bitcoin, solana, ...) they have in their platform. Some of them must be added at the beginning and some of them might have been added later. The nunber of exchanges would be around 300 although I didn't count precisely and each platform would have tens of or hundreds of coins. I can pay for apis if needed (e.g., coinmarketcap and coingecko). Please let me know if you have precise idea and plans. I might NOT answer if it is saying hello or merely saying you can do it. The final result would be something like this: Binance bitfinex OKex ...... BTC Oct 7 2017 .. Etc Oct 7 2017 XRP ..... ....
