Have you heard phrase "Everything old is new again"? So i expect we'll get either modified or rebrand of old-stuff, along with "integrating" current technology trend into cryptocurrency or blockchain. Ordinal/Rune are modification of NFT and currently some new project use "AI" word for their marketing.
I also think that old trends will come back but more successfully and stably, for example Layer-1, Layer-2, GameFi, NFT, Metaverse, Oracle, Memecoins..., at the same time we will have new trends such as SocialFi, Restaking, AI, RWA... The crypto market has enough room for all potential trends that are of interest to investors.
Quantum-resistant blockchain technology was once a hot topic in the bullrun 2017, but most of the projects in this trend have disappeared and I haven't heard anything about them anymore. Perhaps the threat of quantum computers to blockchain has been overblown and has caused many ICO investors to lose heavily. I don't expect them to come back. In this cycle, I want to see more blockchain projects that can participate in serving the real needs of users like Ripple and Chainlink can replace SWIFT or SocialFi can compete with Facebook and Twitter.
