In short, Bitcoin is going through monetization , the stage where an asset gradually becomes money. This process is not smooth or linear. It is highly volatile because the market is still trying to discover Bitcoin’s true price.
I hope you are correct, but I unfortunately don't think this is a "safe" scenario, much less an "automatism".
There are still scenarios in play where Bitcoin stays speculative and will not continue the path of monetization, and volatility reduction stalls. And then there is a certain danger that a lot of what happened to many altcoins will also happen to Bitcoin: it gradually will become less attractive for investors, start to fail to achieve new ATHs, and perhaps enter a long bear market afterwards (>2-4 years). This would be the final death blow to all 4 year cycle theories. And these theories were also part of the "hopium" that would incentive people to invest in crypto winters, so the fall could be quite dramatic.
This situation is not irrecoverable, I would argue that if BTC does not fall below $1000 approximately it is
likely that it will recover, above all if retailers take the chance to recover coins from ETFs and other centralized entities.
But monetization is imo a social process, and thus it depends on the behaviour of the crowds. I believe Bitcoiners can actively try to support this process, using Bitcoin for payments (and thus rewarding merchants who adopt it), and trying out solutions like Lightning and Ark.
In the end, if Bitcoin successfully becomes a global currency the 4 year cycle would no longer matter. It would be relatively stable, and while it would not bring you extreme returns, it's likely it will be an excellent method to save money, better than (stock) ETFs or gold today.
