I think if you have extra money, it's best to choose coins that are in the top 10 crypto markets such as Bitcoin and Ethereum, because these two coins have huge potential and popularity in the crypto market, and I think BTC and ETH are two coins that can gives a sense of security to the holder, and of course you will get big profits if invested in the long term.
I think this is the basis of initial investments in crypto. These are the most liquid assets at the moment and they should be in the portfolio of everyone who invests in cryptocurrency.But there is another type of modern investors who buy various memtokens for large sums because for them it is more of a lottery than investment.
