I say one day a thread here have some statistics about the number of Bitcoins that never got transfered to another wallet... Don't know if the people lost the wallet or just holding...
But for me if users keep holding and do not spending their coin the demand will fall down and also the price was affected it will fall down to.
I agree with you bitcoin ecosystem needs to move and with the way of spending our bitcoin so that it could cycle same as you said. Holding bitcoin isnt bad at ll since we could able to make money with that but its not helping the bitcoin ecosystem for it to grow in the future. If no one spends it bitcoins for sure bitcoins price would be stuck on the current price and we wouldnt see any movement of it.
