No, no, no. I don't think its bad etiquette provided you contribute and share helpful information.
Supply of BTC is constant (fixed) as you said, this is because the remaining amounts to be mined and released into circulation is small compared to the time it will take for them to be mined and released. source
( so supply has liitle effect on the price) rather the demand which is a function of increased usage and wider adoption controls it's price.
The question in my first comment meant "can someone, say 'Satoshi', wake up one day and decide that the price should go up irrespective of demand?"
Is the blockchain truly and completely encrypted for everyone including the originators and key investors?
This question is a concern for most people still reluctant to join the cryptocurrency train.
