I still recommend to invest on the top coins in the coinmarketcap such as ethereum, binance coin, polkadot, matic etc.. because these top coins are still good investments for long term even some of them were old coins but they can still make a new all time high in the future especially bitcoin.
For long-term investments, the top coins are always the main choice of many people,
other than that investing in top coins can be said to be safe so this makes many people recommend it,
but we also still need to do our own research before making a decision
