Bitcoin isn't a store of value (its too volatile), it isn't a currency (too slow and expensive for small transactions), and it isn't even a product in its own right.
If you don’t like it or think it’s too slow doesn’t change these facts.
I agree that it’s not a product though. It is a distributed system that nobody owns.
And yes you can functionally make transactions, but based on current transaction fees it looks like I'd pay $0.22 in fees so I could wait 10-20 minutes for a transaction to likely clear. I'm not doing that at a gas pump, grocery store, etc.
Otherwise I just use the dollar bill as the store of value
Its almost a given that the value you pull out won't be what you put in, likely not close, its either much higher or much lower and that changes frequently over time.
One definite use of bitcoin is to transfer moneys all over the place.
