Tesla already bought bitcoin in January, what we've been seeing this week is just squeezing every cent possible based on delayed news.
Institutional investors jumped in at 20k-22k area, 100% profit in just a few months is a dream for them and will start cashing out if they don't do that already in small portions.
The exchanges are overwhelmed with new accounts registered and that's correlated with what I've been seeing all around me in the last couple of weeks, the last wave of retail investor (drivers, construction workers, delivery man, personal trainers) caught euphoria from the last bullish news and they want to throw all their savings in.
This is not a financial advice, but personally I think there will be a big recession starting this year and I don't know what will happen with Bitcoin. Might be the safest asset to be hold or not, but on COVID crash it seemed actually very correlated with SP500
I'm pessimistic, made good money on this bull run but I hope this helps you to get out of this hype and think rationally long term.
