Many here will not sold their coins at the moment, goodluck to the years that will passed and I don't think you can just sleep your coins there.
It's easy to say that you will not sold your coins. Show some proofs that you really save for now.
Whenever people need fiat they will sell their bitcoins for sure, but may be they are selling in installments and not all of their bitcoins, so only holding is not profitable in long run, you should keep on spending your coins.
