Bitcoin does not need to be spent constantly to maintain its value
Actually you are the one who is wrong.
It's not spending that gives value to something, but demand. Your argument is just a Keynesian lie.
It doesnt matter if you spend bitcoins or store it, BUYING BITCOIN is what gives it value.
Why BUY IT? Thats another question. Buying bitcoin gives bitcoin value, and why does one person buy bitcoin, thats his choice?
You can buy bitcoin to: store, buy items with, donate, invest,transact, etc....
The spending-only argument is a Keynesian bullshit
