The 2017-2018 market was affected majorly by the Facebook Google cartel's illegal ban of all crypto ads.
After the normal early Jan '18 correction, the market plunged 53% - the largest drop ever - in the week after FB banned and then 30% (second largest drop ever) when Google announced ban in March.
So you can't really compare the current market to 2017.
Google and Facebook didn't ban ads until 2018. Not sure how you are comparing that to the rally I am talking about in early 2017.
