IPFS is a way. My next nostr plan is to host a client there. 
Also a great opportunity for decentralised content sharing. 

 I'm in the same boots. This is how the employers slowly breaking the loyalty. Our Technical PM team was just disassembled in the middle of a global telecom project from the VP level. They do not care about what we are doing, just lowering the headcount. 
Look this opportunity as a huge chance to switch. Stay positive! 

 Start slow and make regular relax days. That's the secret! 

 It is a feature of a cryptographic functions that you can not alter the original input. If you change even a character, it would result a totally different digital fingerprint. 
You need to accept this if you want decentralized things. 

 The last one is the cleanest one. 

 I have both now. The NOSTR (rs) relay took 5X more time to set up due to my special conditions on my own hosting and port forwarding. 
Setting up a BTC node was really quick. Reading the documentation took  more time. 
Protip: Blocks-only mode -> really saves you a lot of bandwidth but keeps you up to date with blockchain and can be disabled anytime to have the "full node".
