I say YES for quality ALTs with working teams and good vision. I think Cardano, Stellar are a couple of good ones!
What do you think?
In addition, I think you need to hold for a couple of years!
Of course it is time to buy altcoins. Price Cardano, Stellar and other top coins now looks very attractive and they are good for long-term holding. I also believe that prices in 2-3 years will grow very significantly and the coins will give a decent income.
