3. Also another thought about multimining is, what if you could setup a cron job on the Orange Pi Zero to switch pools every few hours. I know there are auto-switching pools, but it would be nice to say, mine DGB / Qubit on one pool, then four hours later, switch to Verge / Myriad-Groestl on another pool. I think this could be done simply by making a cron job to update the miner.conf and miner.pools.json. I don't know. Then again, maybe it's just easier to use some autoswitching pool or software for this.
