Bitcoin hype maybe getting cold, But mostly i think its because the devs are working way too slow.
The founders are not getting their mind set on the things they should improve on.
There are no "founders" for Bitcoin. And people who write code for Bitcoin are doing just fine. Testing for LN is going full force, and RootStock is making progress as well.
According to what I know If you think like that make progress number of transactions in the crypto market has decreased, and they sell their bitcoin cheaply for profit and other things happen crypto money has little value from the start of trading
