why not, many people say that but not the new Altcoin, it only applies to old Altcoins and is listed in the top coinmarketcap, many I have invested are some Altcoins that have good potential because their development, promotion and team are very active until now, so speaking for investment do not choose the wrong make sure they are still active that's all
But we still have expectations for the top and reputable altcoin. The market has gone through a dark period, perhaps it is screening and selecting reputable altcoins to be able to continue in the market. Spending a small investment on it is safer.
Just choose the top 10 cryptocurrency on the marketcap except for the stable coins because you can't make a good profit from them. Accumulate more altcoins and bitcoin since the market is in dip you can buy it since the price is cheap. Just stay away with those shitcoins if you really want to earn a profit in the future.
