for those of you in need to heat up their room and without the time to search for the next profitable coin, past weekend i've put together a bash script that switches between 3 multipools (trademybit, yaamp and nicehash) and their algos in function of advertised profitability (by pool's api itself).
the script is self explanatory, just adjust hashing rates, pool's user/pass/apikey where applicable and miner's paths.
warning: don't expect huge profits since profitability on multipools is very low lately...
#!/bin/bash
# depends on sys-devel/bc, app-misc/jq, app-misc/screen and sys-process/schedtool
# after starting this script you can execute "screen -r miner" to see miner's output
