The total BTC balance on exchanges continuously decreasing since 2020. This shows that investors are withdrawing and storing their BTC in hardware and cold wallets. They are accumulating BTC for long term. Less BTC on exchanges means less selling pressure.
The reason for crypto exchange holding decrease is simple, the institutions are the major investors and they can't keep the holding on an exchange site not even when we are in bullish market but 70% of BTC holder always sell 75% of their holding when halving effect take place.
The same pattern is find after the 2016 halving and we see a long bull run until Dec 2017.
The pattern of today's market is totally different to previous halving market.
We are still far away from the bull run top. Hold some BTC for long term.
I think you say this because you believe in the prediction make about the BTC market to reach $100K. Well, understand that tomorrow are not promised, this crypto market is highly volatile and the bullish market start when will least expected so it will also end when we don't expect.
Although, there's no evidence that Facebook hold BTC i believe the to be true due to the knowledge of the Facebook CEO and I don't think he will afford to miss out the BTC opportunity when institutional investors invest in BTC.
