Strong hand had been accumulating for more than half a year now during this Bear market. So it is not news that strong hands are buying.
Well, that's not surprising. Good deals are made by buying cheap, and now is a time when Bitcoin is cheap. We can't know i the next few months it could go lower, I wouldn't rule it out, but we are definitely in a clear buy zone if you plan to hold bitcoin for the long term.
The market is still in bear market sentiment so there is always a possibility that the price will decline in the next months until the market transitions to Bullish. I also agree, the current price of Bitcoin is still a discounted price to buy them.
Uninformed retail investors usually do the opposite: they bought above $60-69k and sold recently.
These retail investors are guided by hypes, so they thought that Bitcoin will continuously surge without a break. So when Bitcoin stops from surging and started to correct its market, they are the first ones to sell and those strong hands are the ones buying it from them.
