Yes, Altcoins are now great for investment. Because now there are many altcoins coming with great utilities that's future is bright. Altcoins is performing great today and will perform even more good in future.
Well I agreed that it's good to invest in altcoins however an investor has to be extra careful and do research inorder not invest in a wrong altcoins, of course not all these coins are profitable in a long run, there are some coins that will be abandon by its developers in a later stage, thus only invest in reputable and trusted altcoins with good future potentials, and avoid pump and dump coins especially meme coins,
It's obviously that if the price of cryptocurrencies is bullish definitely majority of altcoins will pump thus enabling it investors to recoup their investment.
