I agree with you. In an event of no one spending, any Bitcoin the price would stay stable for a long time. Mining would die off as there are no transactions to verify and the blockchain would freeze. Basically, everything would freeze until everyone begins to spend BTC again.
mining would never die in my opinion, then the difficulty would drop a lot and people would mine more coins and sell for cheaper prices, mining would still be aroundThat is right. The mining will only disappear if the bitcoin is dead completely. That happens to many coins already.
