Binance has just launched an index feature for altcoin contracts, which is the total of other altcoin contracts excluding Ethereum and BTC! It has higher stability and won't get liquidated due to a spike in a single altcoin. If you are optimistic about future altcoins, just go ahead and open $ALL
But remember not to go all in 🙈
This contract index feature is quite good, as it allows you to clearly see the overall rise and fall of the altcoin market. I feel that Binance may launch more index contracts in the future
