It will likely be a couple years before we see another bull run for crypto. It will need to allow time for people to forget about what happened this year. Right now, every time crypto goes up a little there will be a wave of sellers who were recently burned by the huge drop. It will take a while to get through all of that.
A couple if years? Wow that is a long time.
I think a couple of years of downturn would surprise me. But 3 years of downtime seems conceivable.
The bitcoin bubbles have gotten slower over time and the last one took 1.5 years to turn around.
Plus there is now much more real economies like miners and crypto projects that make a recovery slower.
