Investing on altcoins is risky so you must have risk taking ability first to invest on altcoins. i will suggest you to invest on ETH, BNB, SOL, MATIC, TON These altcoins have a lot of potential for the future. so I would advise to invest in them. These are the top ranked coins in marketcap. so if you want to take risk you can invest in them for long term.
In case of all your mentioned coins there is little or no risk and now a days besides top coins the TON is performing well and hopefully there will be a greater achievement for all of these mentioned altcoins. Individuals often choose Ethereum and BNB but I think if they also choose the remaining mentioned altcoins then their revenue will be more.
One should not ignore any of these coins and if someone doesn't have enough amount then invest little but choose each of these altcoins for investment. One should take the risk but I think there will be no risk in investment of Ethereum, BNB, Solana, matic and TON because their success is increasing daily.
