I think btc price is not directly correlated with difficult, is the opposite.
Difficult needs to adjust to btc price, because less efficient miners need to shutdown their equipments.
You are technically correct, it is a new BLOCK that is generated every 10 minutes.
However, that doesn't change my conclusion: The is very little correlation between price and difficulty.
Price is determined by the public agreeing on what they think a Bitcoin is worth - nothing else.
And what they think a Bitcoin is worth is partly determined by changes in the difficulty. Not totally, but partly.
I would agree. As mining becomes more difficult with specialized mining equipment required, people will be more likely to buy instead of mine to acquire the BTC they want.
Yes, but also especialized mining companies need to sell all their huge earned bitcoin to keep growing the business. When you only have small home miners, they usually keep the btc for them, until the have a lot.
