I have a recent use case for you.
I recently sold my house, closed on it at the end of Jan. The title company cut me a check for 76K after the deal was done. I go to my bank to deposit the check. The bank tells me... I can't access the full amount for 7 business days because it's over their deposit limit. So essentially, I can't use my money via the bank even tho it's clearly mine.
With bitcoin, and cryptocurrency in general... when it's adopted by more industries and sectors, what happened at my bank will be a thing of the past. No matter who you are, you want access to your money instantly. Then when you factor in the players with MAJOR bread and the capability to move millions without the hassle and hoops that banks and financial institutions make them go through now, it's easy to see why huge companies are buying in to BTC now.
