Yeah switchers are always chasing and behind the hot coin. Plus a shit ton of other people do the same switching.
I mine 1 or 2 coins zec and a shit coins at the moment and my 16x 1080tis are between 2.25 and 3.25 a card before power cost.
profit switching is a waste of time always chasing down money
what i do is have 2 rigs that are dedicated to mining shit coins (one amd one nvidia)
then all the others mine eth/zec might do some xmr soon
hoping for that one day those shit coins become something is better than chasing those pennies
also I like to mine a shit coin and sell enough to then hold.
RVN I mined 13200 coins sold 8000 hold 5200. When I count power used and
selling the 8000 at 0.0000055 on average was about 0.044 btc. sold the btc at 9900 so 435 cash. power used was about 100
so I am 435-100 = 335 in the black with 5200 coins on hodl.
They are listed at 2700 for 0.000049 = 0.1323 with 2500 in a wallet.
My new shit coin I have about 55 of using 2 1080ti to mine it.
