Altcoins are good and profitable for the few who understands them and, much more important, who know when to sell them.
On the long term most altcoins simply go down and a few better ones may remain profitable against dollar, but, by far, no match for Bitcoin.
So yeah, I agree with the previous answer: are you joking, right?
And even more: if you want to ask about altcoins, please do so in the altcoins related part of the forum, not here.
Very true. Knowing when to sell an Altcoin is the main deal. One of the challenges with the Altcoin ecosystem is that there is this constant creation of new cryptocurrencies and it makes it more difficult for people to know which is more reliable or let’s say “safer”. There are alts that have and will make it over the years but as time passes many will be shaken off back into the dust. Bitcoin on the other hand is just one and hence its uniqueness. It’s less likely to fail you unlike these alts.
