I prefer to invest in Bitcoin. If I actually want to diversify a little, then I can go for strong projects that have their own smart contract and network, such as ETH, BNB, Matic, and Solana. If I want to invest in meme coins too, I will choose Doge Coin. The fact is, altcoins can be so unpredictable compared to Bitcoin, which has two known seasons. If you buy some Bitcoin during the bear market, you are sure to make some profits during the bull market, but if you invest in altcoins, you are not so sure of the coin that can have a huge price pump.
