I think it is foolish to expect such things from Altcoins, because the disappearance or devaluation of Bitcoin means the collapse of the digital currency and may cause the collapse of the Chinese block, but we can expect better and more reasonable expectations than Altcoins. One of these expectations is the development and expansion of the Chinese bloc in other areas such as medicine and agriculture. Atrium, Neo and IAS are moving in this direction, and we may one day see these platforms as global giants. Act in different fields
Bitcoin is the mother of all cryptocurrencies that exist today, so I don't think anything can replace or match it, even before that many people thought ETH would be able to match it but that's all just an opinion, I hope you never think about the coins that in the future will can replace bitcoin again
When you hear about cryptocurrencies, then in someone's mind it is certainly related to bitcoin, even though there are many altcoins in it, we can see the level of trust from the total market capitalization that exists, where bitcoin dominates. bitcoin seems to be a brand for cryptocurrencies so it is difficult for altcoins to replace them.
