In my opinion, coins that are worthy and potential to invest in are Binance, Ethereum, TON Coin, Solana and Polygon (MATIC), and if you have 5k then convert your money to 1K for each altcoin, and I am very optimistic that these five altcoins can provide profit in the future.
BNB, ETH, and SOL are the safest bets in my opinion. They have already established themselves as one of the top altcoins and are often considered to be next in line with bitcoin. They also seem to exhibit a relatively stable price as of now. I would personally increase the amount I’d invest in three coins.
1k wouldn’t be my choice as I am not yet that familiar with the two other coins and therefore cannot give my opinion.
