I have been testing the geth client for a few days and not once it has been in sync with the chain (> admin.chainSyncStatus - currently 5h).
So, if I want to install a client it will take at least hours to make it fully operational? I have understood that you have to be in sync with the chain in order to mine, is the same true with handling transaction and contracts?
The amount of time needed to sync is relative to chain age? What will happen with new clients on the live-net in 3 years for example?
