I was wondering where I could read up more on mining and if it would be worth building a mining rig using 6x 1050 TIs atm or if it isn't worth it anymore? (To mine ETH, ZEC and XMR)
First start by reading the forum rules
https://bitcointalk.org/index.php?topic=2415854.msg24714338#msg24714338Then post in the altcoin section and read up on mining alt coins there.
Good Luck.
