Ok so due to BU the size of blocks can be increased which will result in faster transaction confirmation and eventually less price so my question is (correct me if i am wrong) What's stopping some another stupid developer to create another fork in which he increases the supply of bicoin lol and majority of the nodes start accepting that? May be then all the hodlers will be doomed?
In this case a lot of the conspiracy theories. Because this will have a relationship between the miners and the stupid dev. Without the backed from the miners, the stupid dev can't do anything. because they're gaining a permission to fork the chain according to the consensus rule.
The key is the miner itself.
