Answering the topic - no, I didn't miss the bull runs that took place in 2020 and 2021. Figuratively speaking, I was sitting in a big flying rocket with other Bitcoin (and Ethereum) holders. I can say that I am already used to cryptocurrencies in my wallets. They are an integral part of my finances and are likely to grow in the long term, which is why I am almost serene, owning the top-rated coins I invested in. Nevertheless, I want to trade and make profit again in the future.
Finding a suitable entry point is not a trivial task. We can only assert about fundamental incentive factors (such as halving, hardfork, etc) which most probably will have a positive effect on the price. But overall, you're right. Now is good times to accumulate BTC and other promising coins.
