I don't understand why would you pay someone else to run a full node and don't just run it yourself for free?
You cannot run a node for free. Unless you steal bandwidth and electricity which is obviously incorrect
I'm paying 8 EUR a month to run a Classic node on a German VPS at the moment. It feels pretty reasonable to me, I get a ton of HDD and unlimited bandwidth.
What's the host?
Is it posible to run a full node in pi? I need a external usb drive.
Computing power wise and power wise, raspberry pi is feasible.
It is for now, but its 512 RAM is very small and its CPU is very slow, so validating the blockchain alone takes several weeks.
It's feasible, and there are people running nodes this way... But obviously not on the 512MB RAM Pi B
You've got to have a Pi B 2, which has 1GB RAM.
For now you can even run the node solely on the Pi, using a 128GB card. You can even run it portably, on an external battery, using wifi or a 4G connection (I haven't tried this, but it's not an impossibility)
