The 2017 bubble was indeed an expensive learning experience.
You cant call that a bubble because a real bubble means it pump and it dump down to zero or in short it has exited unto scam . but in the case of crypto . the year 2017 is only a normal year where crypto shows a sign of recovery and it continue until the coins reach their new ath's .
But at that point, bitcoin is really going on a parabolic rise that upon closely inspection, it was a bubble waiting to be burst. Some might not recognized it, but I'm assuming experienced traders and smart investors really knows what going up to that market at the end of 2017.
Now after it . the next years were kinda bit frustrated because the movements of the coins are pretty confusing . one time they are stable and after the next few days they will drop then the next few weeks they will increase a bit and then drop again .
And this is where it gets more exciting, after the burst, people don't know what to do, they continue to sell offs pushing the price down to a all-time-low (ATL). So for those who are not familiar, there's also this thing called ATL, but don't be scared though, this market works on cycle so after the capitulation, we might see a good recovery, it may go on months or years, it doesn't matter, eventually we will go and hit another all-time-high.
