Hi im using the 0.13.0 version, with my 0.12.x wallet (so the pre HD era) because I was too lazy to do the whole thing of auto sending me the coins to a new wallet because I would need 2 computers. Anyway im still using the non HD wallet. I would like to know what is the limit of non HD wallets. I remember reading about how it can run out of sending or receiving addresses. Does the program tell you when you can't generate any more addresses? How can I check how many addresses does the wallet have left?
With the old Bitcoin Core , when a wallet is created each private key is generated individually (100 of them are pre generated in advance) so you have to make a Backup after each additional 100 transaction you make so no there is no "limit" , you just have to take backups from time to time .
Also what is the way to update to 0.13.1? Just install on top of the 0.13.0 and that's it? When I run 0.13.1 node I am helping to activate segwit already or do I need to do something else? or this is only for miners? Sorry for a lot of extra mixed questions.
Backup your wallet.dat , Install the new version and that's pretty much it. Running a node won't help doing anything (except helping securing the bitcoin network) , so yes this is only for the miners.
