I have done 5 transactions. It's cool, but the limits are very low, like 5-10 dollars/euros. I have a hard time understanding why use mostro instead of Robosats.
RPi 5 is cool, but used mini pcs are way cheaper. Go for something with 16gb ram and a decent processor if you also want other things like lightning node. You'll probably need to upgrade the original storage to nvme 2tb.
I once had a job that we had a rule. If the tank was below half, we had to refill before going home. If the tank reached a quarter, we had to refill immediately. I still do that with my cars.
Dual boot #rEFInd, #debian and #macOS, on an old macbook air 2014, i5-4260U 1.4ghz, 128gb ssd ram and 4gb ram. Loving to learn about #Linux, I'm never coming back to #Windows!
Maximum I could do was 5 days. It gets much easier in day 3, the cravings basically disappear. Regarding preparation, nothing better than eggs and bacon to kick start the ketosis!
Just don't let people prepare food nearby, smells awake the lion within 😁
Honestly, I find it easier with just water. Usually there's no need to have electrolytes, and sometimes they make you hungry. Also, it's easier if you're in ketosis before you start the fast. Good luck, you can do it!
