What is the crypto projects in top 20 that will fail to retain their position in the next bull market? There is a saying that in every bull market new projects will take over the top 20, do you think another project can rob the positions that Avalanche, Matic, Polkadot and Solana tomorrow?
of course every time a bull run occurs, then the top 20 on coinmarketcap will change, only Bitcoin will remain top 1 on coinmarketcap, therefore it is better for you to invest in Bitcoin 50% of your portfolio and the rest in altcoin, because Bitcoin will definitely give you profit (Bitcoun price will inevitably create a new ATH price every bullrun), so you have nothing to lose from investing in Bitcoin for the long term.
