it is chasing the hot coin = bad.
and if you are mining on pools that kill you when you jump you lose the work .
Say you have 500 shares of coin x work on pool 1. say 10 minutes worth.
hot coin comes up you jump. many pools kill your work when you jump so those 500 shares or 10 minutes of work are lost.
NOW make a jump every hour chasing the hot coin you may lose your last 5 or 10 minutes of work on every jump even worse if the pool is making 1 block an hour
and you jump 24 times in a day. you could lose 50% of your work. Since each coin you jump to makes 1 coin an hour chances are a large loss of time can happen.
this is true for many pools but i would think that mininghubpool (for example) would choose pools that straight up pay per share and allow one to come and go at will without affecting payouts. even still i have limited my various workers on mhp to one algo (based on the gpus, amd RXs on one 1070/1070ti on another, 1080ti on a third) and let mhp switch pools which use that algo. as a strategy that might turn out ok, or it may suck.
ill let it go a week or so and see what happens.
