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?
This is what every altcoin dev is doing. The price of one coin is not decided by the dev team nor exchanges. When one developer comes with any modifications on bitcoin's coding then that will be just a new altcoin, nothing more. That will get its prices based on demand from crypto people. You can not have same bitcoin system but with altered parameters.
Your statements will not make bitcoiners panic as these types FUD are classified as rumors and in deep analysis people will make conclusions about the possibilities. Frankly, I laughed on reading your post rather than your expected panic.
