Ok this is pretty basic question but surprisingly I tried googling it but didn't find the answer. So like always I turn back to my people for this answer. Why companies like binance choose certain cryptocurrencies for future trading and why they don't provide all cryptocurrencies for future trading.
Cause not all have a good trading volume and this is one of their main factor in launching future or derivative marginal trading for certain token or coin. The need of volatility and market buyer and seller is important to provide a big ratio for the future trading. Well other factors might depend on their criteria but surelt this is one that fit for that.
