What happened was repeated 3 times, and those times were related to the end of a cycle or the beginning of a price cycle, and therefore it is logical to understand that its impact was bad on prices by leading to a correction, but it is wrong to rely on it as a long-term influence.
At the end of 2017 when the fees went up, the price of bitcoin was much higher than it was at the beginning of the year. Likewise, the same thing in the middle of the year 2022.
As far as we can conclude that high fees mean that a short-term correction is expected, but it does not tell us anything long-term.
There is a small problem now is that we do not know whether the increase in fees will be instantaneous or sustainable?
We seems to be back to "normal", not the 1 sat/vB transaction fees, but I think it will be like 10 sat/vb or higher now. I know, it's has balloon so much and we all know who is the culprit. And as you questioned it, will it be sustainable? or the bitcoin core dev team will do something again similar to 2017 debates and what not.
And we are not even in the bull run yet, so just imagine what will be the fee when we starts going parabolic. And what will be the entity behind this spam attack will do, for sure we all know that their aim of. And so if they manage to time their attack again in the bull run, it's going to be a big problem for average joe investors/traders as we will have to pay higher fees which is not good.
The price though is still on the sideways, $26k-$27k in the last week or so.
