I don't think people change crypto, people only use crypto for their own purposes. Basically, Satoshi made Bitcoin as a digital currency but people made it as a digital asset/investment. However, it doesn't mean people change it, people only use it with a different purpose. By the way, for new altcoins, people have improved many things for their fundamentals, it may be a bit different with Bitcoin. But once again, I think it doesn't mean people change it, people only improve it!!
