Any useful crypto features that were developed in the last say 5-6 yesrs will likely be ported to bitcoin I suspect. The main reason is that buildkng on other blockchains is similar to building on sand. If you can't 100% and blindly trust the chain to keep functioning and not stop/censor transactionsitts unlikely to work long term.

Bitcoin is superior in that sense and ultimately will attract value as I see. The next wave of apps are already being built onbitcoin. Many draw from the experiences and failures of altcoins as I see.
