Well, if you're a long term hodler, you will not be tempted to sell your Bitcoin regardless of the fees for every transaction. Though it's true that many investors decided to hold at this time due to high fees, but it doesn't mean they're going to hold for long. It's just that the fees are hindering them to transfer their Bitcoin.
