A few comments.
1 - BTC is around 50% for the year. So even it was to remain at 30K for the whole of the year that's still a 50% per annum gain. (as opposed to cash which pays zero return and would be down over the year due to dilution of value due to money printing).
2 - Zoom Out is the best advice I can give. If you believe BTC has a long term future, then you must also believe t will only go up long term. And so all these movements now will be almost irrelevant in dollar terms, compared to future price points.
3 - Most, if not all people, who believe they can successfully "trade" by picking short term movements are kidding themselves.
4 - In case anyone is wondering, this time around I have hodled all my coins in cold storage. And then physically locked up my access device. The reason being is that I wanted to make my long term decision un-influenceable by short term sentiment. I'm in hodl mode until at least the next halvening event (likely in 2024). And then, based on previous halvenings will be looking at selling perhaps just a little in the subsequent 18 monts (2025-2026).
5. There is a huge amount of systematic auto-buying from many retail investors, which will help provide a stable demand (and indeed makes price go up a lot more once any larger buyers enter). Many huge institutional buyers will start nibbling away. And then suddenly, as supply/demand dynamics equalize, we suddenly will see a FOMO driven movement sharply upwards again.
6. Some of the recent sell off may be driven by hedge funds who have already made enough gains for the entire year based on BTC+alts, and want to simply lock the gains in. They could in theory go hit the beach for rest of the year, and chill by the beach until next January 2022. But they won't. The incentives, and the natural drive to make more, will bring them back in again over the next few months, as soon as they form the view that prices have "bottomed out".
