Yes I agree with you that investing in top ten altcoins is a good decision to invest. If the top 10 coins include meme coins there then I don't want to go there. Also among the ten coins are several coins that have not increased in value much. Among the top 10 altcoins my favorites are Ethereum, BNB, Solana coin. These coins have performed well recently, although the price has dropped slightly. But I am optimistic that these three coins will perform well in the coming bull season. So, I think three of the top 10 altcoin will help to spread the investment of coins and get much profit in future.
But the top 10 altcoins cannot give you significant profits. As you said it will be difficult for coins in the top 10 to record increases of hundreds of percent. Only ETH, BNB and SOL have good profits. Other coins such as XRP and ADA do not provide profits. USDT and USDC are stable coins. DOGE and SHIB are meme coins. I excluded TON because the project only entered the top 10 in the last few months and not in the last year.
