In a bull run, all of the projects are being benefited thus, the coin of that project increases by at least 2x or even 3x.
Top projects? Top 50 coins? Top 100 coins? Some Low market cap coins? You name it, they all increase.

However, the most famous coins or those at the top are the ones who will benefit the most in a bull run, and I'll specify Bitcoin on this one because why not? I mean it's the top cryptocurrency, and most of the altcoins' prices are moving the same as how Bitcoin's price moves. Another one who will benefit the most are the projects who will be the hype during the bull run. During the last bull run, it's the NFT's who benefitted hugely because of how many investors invested into it. Some turned out as scams, some are still developing and some just rug pulled.
