mining works by using your electric to power a device that does complex math to give a block a strong secure ID
the thing is the cost of mining differs depending on location. not everyone will/can profit at the same time
if you cant get cheap electric and a cheap device to mine. it wont be profitable
even if the market price moves up by 3x-15x to make it affordable to mine. the competition also moves up..
so those that can afford now at 1x.. will 2x 3x their devices and electric costs to beat the competition when the price moves up by 3x
however this upscaling of hash competition is a 6month-12 month thing
thus if you are a hobby miner in an area with high electric you only have small temporary opportunities to profit when prices move faster than the scaling up of competition
that said. there are times where lots of altcoins are speculating high at different times so people jump between altcoins to take different opportunities at different times
your best bet is to live in a low electric cost area to get best and most opportunities
if you live in an expensive electric region opportunities are reduced/die out, even if you were altcoin jumping daily
EG
mining in iceland costs $0.12 in electric per hour per device (3kwh at $0.04)
mining in hawaii costs $1.44 in electric per hour per device (3kwh at $0.48)
(reminder there are ~2m devices mining bitcoin thus its why bitcoins market is worth many thousands instead of cents/dollars)
if you are in a low electric cost region and have a cheap device that gives good hashpower you can join a pool and take a decimal amount of coin reward that equates to your share of your involvement
