I am working on the text, Mastering Ethereum and working on the part where one has to download the blockchain. Now I elected to use geth because parity seemed to be getting stuck on blocks for almost an entire night.
Anyways, I have been doing the download using geth and I believe I am on the right path , the age of blocks started off from over 2 years and now it's down to under a minutes. Now looking at my console if all transactions are less than a minute old.
1) Is it safe to say I have finished downloading the block chain?
2) Can I close this page and when I want to continue or update just run the geth.exe again?
3) If i am not finished, and I close this page, will running the geth.exe resume where i left off?
