do you think the Bitcoin cap can't be raised if there's a need for it and users overwhelmingly approve? How is this even related to PoW vs PoS at all? in both system, the cap CAN be raised period
Within Bitcoin PoW the delegates are also in control of the protocol itself. the power dynamics are split between the miners, asic manufactures, users and nodes, and developers. Additionally, Bitcoin has a very large network effect where a critical mass has been created to introduce many competing interests and involvement unlike with many alts.
Within DPoS you have a mixture of the users/stakeholders and delegates/developers controlling the power with a very dangerous arrangement of only a few developers controlling most of the direction compared to Bitcoin.
Don't kid yourself, the users, since they are overwhelmingly in favor of the change, will accept the cap raise. The miners will do nothing and also accept the cap raise, because the miners will usually do whatever the users are in favor of. Also, since it's actually beneficial to the miners to raise the cap, why would they oppose it. So there, your Bitcoin cap raise, done!
That's sure .
