Op. It seems that your general idea is just to use bitcoin on daily basis and I can agree with you. The problem of this solution is however volatile bitcoin nature. As you may know not that long ago bitcoin price was just about around $200 now we are almost at $300. For many people who remember 'old' higer bitcoin price this is unacceptable to spend bitcoin now.
Thats why I treat bitcoin like gold and I wouldn't go around doing groceries and having a cup of coffe paying with gold. I'll let these damn whales do the spending for now, when the price stabilizes at 100K i'll do some shopping.
