The official
BTC source code is currently updated by a group of Devs who contribute to the
open source Bitcoin project.
Exactly how does BTC development continue if the current group all quits or dies?
(For example) Who takes over the ghost ship if COVID and the next 19 variants get a lot worse?
Edit: Updated based on early responses:
Technically Bitcoin development stops if all the dev's stop or leave....
Thank you, now we are very close to the exact topic: A
small group of core devs actually release the code, who takes over if they are gone?
It is an interesting question to think about. While abandonment of Bitcoin maintenance could happen if something catastrophic was to take place like an alien invasion or something similar, the likelihood of it happening is low. This is because as long as Bitcoin is valuable and it's worth more than $0 people are going to try to use it in whichever way they can be it through mining, consensus etc.
Bottom line is as long s there is value associated with Bitcoin the above scenario is. highly unlikely to take place.
