Possible dumb question: If BTC and other blockchain currencies are developing technologies, how can holders be sure that the behavior of their coin(s) will stay the same as when they bought it?

I fundamentally don't understand how something like BTC can still receive any changes. The way I understood it is that it works and will always work the way it was designed when it launched; any changes seem to defeat the purpose. Clearly there is a big fundamental gap in my understanding of cryptos right now, I appreciate any attempts to enlighten me.Despite the emphasis on decentralization I sometimes hear that BTC is 'changing,' maybe I misunderstand, though my question still applies in a broad sense to many other crypto currencies who are openly being developed and altered whilst people hold them, like Cardano or anything else with a roadmap.
