Earlier quoted context omitted.
People were using money online just fine well before Bitcoin, and even today, actually using BTC for non-investment purposes is a tiny minority. What exactly makes a dollar or euro less "online/digital" than a bitcoin?
Speed of iteration/development/experimentation. You can't fork EUR/USD, experiment with it and see if it works better than the existing EUR/USD. You can with online currencies and people are doing just that. Most will be failures in the same way that most new businesses/startups are ultimately failures. BUT the difference is there is actual experimentation with money now in a way that there never was before.
99.9% of this "experimentation" is simply companies tying ownership of a token to a permission to access a web service. And the remainder of it are clueless tech brained morons finding ways to re-invent financial instruments (like residuals, profit splitting, and derivation) that have been around for hundreds of years. You don't have any new insights into financial systems, you just want to be at the top of the financial system and collect rents
