It doesnt exactly go into detail and many of those functions like getinfo() are deprecated. Like running in pruning mode I run the normal bitcoind? I'll still be able to generate new addresses for each transaction? Will I be able to use it as  "hot wallet" and then send it to my cold storage wallet after it gets enough confirmations? Will any code I write for pruning mode still work on a full node when I get a VPS with plenty of space?
