The 47th President of the United States bought $47 million worth of Bitcoin when it was worth $100k+. He set an example that you don't have to wait for the price to drop to buy Bitcoin. If you have a long-term plan, you can buy it even during a bull market
Yes it is true that you don't have to wait for the price to drop to buy bitcoins, you can enter the market and buy bitcoins at any time according to your own means i.e. with your own income.
But you mentioned that the US bought $47 million dollars worth of bitcoins, did you notice they didn't buy bitcoins, the US bought $47 million dollars worth of WBTC bitcoins. It should be understood that BTC and WBTC are not the same. Bitcoin is real decentralized while wbtc is ethereum based decentralized. Take a look at this tweet from Max Keiser, I hope you can understand the difference between the two.
