Cryptocurrency technology hasn't even reached 10% of its potential in the global community, and you're already thinking about something new and breakthrough. It's like buying a new phone and dreaming the next day about an even newer phone before you've even tried it. The only breakthrough, in quotes, is CBDC, which wants to completely centralize digital payments and kill cryptocurrencies with their complete substitution. Is that the kind of breakthrough technology you're waiting for? 
That's certainly true, mate. Crypto/Blockchain tech is just getting started, so it's going to take quite some time before something new and revolutionary replaces it completely. I still think Quantum Computers will improve the performance and cost-efficiency of existing blockchain networks. But it would be just an improvement to an existing tech. Nothing completely new from scratch that will blow your mind. The world is struggling to recover from the negative effects of the COVID-19 pandemic and the Russo-Ukraine war, so we can't expect any advancements in technology until the tide is over. Who knows what the future holds for crypto/Blockchain tech? Just my opinion
If we trust all of our investments into crypto then when that happens and something better comes out, then we are going to end up with a limited amount of chance to survive in the crypto market. Many people will leave this market and go to that new market and that will crash the prices which would be hard. So all in all, it's better to follow the market movements and where people move to.
