target different sectors, one best coin from each sector, but not more than 5 max coins, u may add a meme as well. more than that imo is over diversification. Increase investment

I was just thinking about like holding multiple coins is best or holding only 2 to 3 coins is enough like write now I'm holding multiple coins like $Turbo 60$ $Brett 100$ $W 330$ $Sei 330$ $LDO150$ I'm it confused what's best?
