...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)
I've heard it isn't worth it because of how the difficulty increases in mining, that it wouldn't really "pay itself off", and I've also heard that it would pay itself off and I could easily sell the cards in the case that it would not be profittable mining anymore.
Worth it , not worth it , profitable , not profitable , , return of your investment... there is a easy answer for your question from another topic :I DONT UNDERSTAND WHY NEWBIES KEEP ASKING THE SAME QUESTION " ITS TO LATE TO START MINING , IT IS STILL PROFITABLE ?"No one can tell you !
Always going to be a 2 group of ppl who telling you it's ok go for it , or dont bc you just wasting ur money !
You have to make a decision for yourself !
Do your own research !
No one can tell you for sure what's going to happen with cryptocurrency !
No one can tell you it's going to be profitable for you or not !
No one can tell you how much profit you going to be able to make ! ( if you can make any at all )
No one can tell you the ROI ( return of investment) time !
None of those calculators you are seeing on the web can tell you what's coming tomorrow , months later or 6 months later !
Those calculators telling you about today , at that moment when you typing in your information !
It's little bit of gambling , you must to decide you want to play on the lottery or not
