BTC is the coin that makes it through the decades to come, due to the reasons you and others described.
Our support should go to it and LTC, in my opinion.
These two are the examples of what to learn and follow.
Litecoin and Monero. I feel they will be the most decentralized cryptocurrencies on the market after Bitcoin gets compromised. They will be our only salvation. Bitcoin's fundamentals are already dying with the introduction of spot ETFs. Wall Street has taken over the market.
Institutional investment companies (BlackRock, Fidelity, VanEck, etc) are already accumulating large amounts of BTC. Maybe they'll own the mining industry as well? I hope not. If all goes wrong, the community might launch a fork of their own. Problem solved.
