Admittedly I've only been around the crypto space just under 1yr. Been a stock/commodity trader for close to 10yrs.
As for the 2013 crash, it was the wave 1 top. I'm hearing from experts I follow that we're in macro wave 3, and we just completed the 3rd wave of that 3, meaning next wave up is wave 5 of 3.
After that this would point to a wave 4 correction similar in time an duration to the wave 2 correction beginning 2013 you talk about. A correction very deep and long in time.
However, it's possible we've already topped that leg, very tough to know.
Regardless a "time correction" such as beginning 2013 like you refer to is needed in crypto. What it will do is weed out some of the hot activity as traders shift to another macro market to participate in (US stocks, commodities, etc). Big action coming in those markets.
Also, crypto is complicated. So if it really is here to stay, the general public will need to learn it and that takes a lot of time for the masses. Hope that helped and answered your question.
