The year 2024 will be a profitable year for altcoin but that will depend on how bitcoin soar in price this year. If bitcoin could skyrocket in price as expected of it, hopefully all top coins "1-100" will all be profitable in price. Although the profitable coins that I have on my watch list are: Eth, Sui, Arb, Matic, Bnb, XRP, and Polkadot.
Hodling and trading them by 2025 will not be a wrong idea because that will be when bitcoin will be giving us a new ATH, and almost all the altcoins will skyrocket more than expected as a result of that.
