I'm planning to run two nodes sometime soon, but I have to decide which solution is better.
To build a physical machine home or get a VPS.
And here comes the question about the Internet bandwidth.
I have a shitty ADSL line with no more than 7Mbit connection, in the best cases.
What is the real bandwidth required for the Full node and same question for the LN node, does the number of open channels affect the bandwidth.
I believe it heavily depends on the number of simultaneous connections you'll allow. (Default = 125?),
https://bitcoin.org/en/full-node#reduce-maximum-connectionsFor the exact requirements on full nodes, see
https://bitcoin.org/en/full-node#minimum-requirements , which states
A broadband Internet connection with upload speeds of at least 400 kilobits (50 kilobytes) per second
As far as lightning goes, i would assume so, but perhaps someone with more knowledge than me can answer that.
