altcon have their section, but i can tell yu that what you want to do does not work anymore, it's better to mine bitcoin directly
in the past the alt mining + exchanging for bitcoin was a better way to acquire many bitcoin faster than simply mining bitcoin
then, many scammers has appeared with many scam coins, and the altscene faded away slowly, now the section is almost dead
it's sad i remember that i had a great fun instamining almost all altcoin of late 2013 and 2014 with a gpu rig

Altcoin mining can still be done but you need to do your research first. There are some new altcoins that might have the potential to succeed.
