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
