Personally, Bitcoin has done very well from last year till now. It made good twice bull run. And it is already high now. I am personally not sure if bitcoin will be going up the more any moment. So, maybe we need more whales to be buying at this time.
Yet, buying at high in a trusted coin is better than buying some random shitcoins without clear road map.
If the big boys are buying rather than selling, that should tell you of what's to come for Bitcoin. The objective price for this bull run is $100K and bitcoin is around 80% - 95% away from that price target so they see the current price as an opportunity. I used to think $20K was too high for Bitcoin back in 2017 but it had stayed above $20K for nearly a year now. Microstrategy is a firm that knows what they are doing. Thru won't buy unless they know the market would appreciate.
