The internet traffic is quite big for one full node already
Over the past 106 days, my node (on clearnet) downloaded less than 1 GB per day, and uploaded 23 GB per day on average. I've set it to allow much more, so it's solely limited by the demand for data. For a server, it's not that much. At home, I don't expect my ISP to complain about uploading 23 GB per day continuously, but I also wouldn't want to find out.
I didn't know the numbers, thank you for this, very good information.
I think that with this kind of traffic (especially upload) the ISP may start keeping an eye on
you the user, since I don't know of too many apps that generate such traffic apart of Bitcoin and the P2P file sharing services (like torrent).
