Miningrigrentals is a hashpower rental service where you can get a mining rig and point it to the pool. To mine Firo on Nanopool, please register an account at Miningrigrentals and deposit some funds. On the top right corner click your username/favorite pool/add a pool and set the following:
Name - Nanopool (optional)
Type - FiroPow
Host - firo-eu1.picopool.org:22222
Workername (-u) - YourAddress.WorkerName/Email
Password (-p) - x
Eworker - leave it blank
Notes - leave it blank
Make sure to use your own Firo address, otherwise you will not receive your mining reward. Use a simple worker name to identify your Rig on the pool. And fill your email to receive alerts from the pool if your Rig goes offline, otherwise use a passphrase to access your account setting on Nanopool.
Don't forget to set failovers. Starting from the beginning, create another favorite pool using the same data you used first time but different Nanopool host name. See all available host names here.
When you're done, click on Rigs tab and pick out FiroPow algorithm. Choose a Rig from the list and set amount of hours you want to mine. Once done, hit Rent Now button and add at least 2 saved pools. Also, in order to avoid high latency, check Nanopool servers you set and the Rig you chose are close geographically. Click on Instant pay Now button when everything is completed to start mining.
After about 30 minutes of mining, go to the pool main page and on the right top corner find Address filed, fill your Firo address in it and hit enter - you'll be redirected to your Nanopool account.
