Sites like whattomine look at difficulty, block reward and coin value. When a site like that tells everyone [insert coin here] is the most profitable, everyone switches to that coin which jacks up the difficulty and makes the coin no longer profitable. It's a paradox.
good analysis .
@ op you got to a coin early before the switching Killed it off.
Switching programs always chase the hot coin and are always behind the wave.
You should not use them.
You should pick coin A ------ stable money maker mine it six days in a row and sell it.
You should pick coin B ------ A shot in the dark mine it 1 day and hold it or list it at a stupid high price on an exchange.
Say it is worth 1 dollar when you mine it. list it for sale at 10
Every 7th day mine it and list it for sale at 10x the price you mined it. This is your I made a fucking score coin.
Coin A is your it pays the bills coin.
Say you do xmr with that card to pay the bills 6 days a week and do zcl 1 day a week listing it at the high price. If zcl takes off you score.
and xmr/monero is paying the bills for the six days a week
