Currently I will be buying and collecting bitcoin as the price of bitcoin has gone down and I feel it is a good time to collect some bitcoin. There are other good altcoins to buy as well like Ethereum and BNB so these 3 coins would be my choise.
I dont have much cash right now so currently I would only be able to buy one of it and my pick would be bitcoin.
Most people do choose the three coins you mentioned to buy and I think it is the right choice considering that these three are the top coins,
actually there are still some coins worth buying like Matic, ADA, and other coins
