Probably. Between new demand worldwide (e.g. S. Korea, Brazil) and institutional interest due to legal changes in places like Japan and Australia,
demand is soaring.
Couple that with fixed supply of new coins and reluctance of holders to sell and you're bound to have rising prices.
My favorite local sources have already run out of coins.
We also had the halving. That was priced in at the time but it had to catch up sooner or later.
