lol. You only have to download the chain one time - forever.
People sit in their living room all over the planet streaming movies every night and you worry about 2MB every ten minutes? Clearly you failed your math A levels.
Just another example of a person who clearly has no idea what he's talking about. No idea how I missed this idiotic post on my first visit to this thread. You obviously don't even know how nodes work. why nodes spend this much bandwidth. Seems like the original statement was correct (more or less) and I had misinterpreted it.
No you don't just download the chain and be done with it. A full node does not only download blocks - it also receives and relays unconfirmed transactions and sends out blocks to other SPV clients.
Your node could easily send out terabytes of data in 1 month if you don't restrict it.
Correct. Even nodes with lower upload connections and total number of connections send out a lot of data. In April my node spent ~150GB of data.
Update: Removed initial statement as it was a misinterpretation.
