For start - BTC is a currency not investment, but most people dont get it. Why its important?
The more BIG companies adobt BTC - they do it trought Bitpay Coinbase etc - that means -
they SELL same moment they get coins.
Big companies taking BTC are not makign price raise, actually the bigger the company - the worse price will be.
This is why soon price of BTC will drop - more and more big companies are taking it now so soon indeed it will be a currency - but it will be nowhere near your expectations of 1k$ a coin or even curreny 600$.
Dont hate on me, shoot your opinions
No. Increased adoption means (by definition) a higher BTC transaction volume and thus increased demand for BTC. This is true even if all merchants immediately convert their BTC to fiat. There will still be an increase in the price because a greater volume of consumers will have a demand to hold BTC at any one time.
