Well, I wouldn't call myself a "crypto expert", but I have some experience with trading and analyzing charts using technical analysis (TA).

This post of mine might help to put it into perspective.

There are also many fundamental reasons why this dive in price has happened. Among them:

1.) more and more pressure from governments in Japan, South Korea, India, etc. to increase regulations on crypto transactions.

2.) all the speculation around what's going to happen with Tether (USDT) and how it might impact the crypto markets if it's confirmed that they haven't backed their Tether with $USD at 1:1, as they have claimed.

3.) people tend to be in a fearful state and overreact to markets when they experience strong corrections like we've seen with bitcoin and the general crypto market. Media (television and social) reports tend to be a big influence when it comes to this fear.

And there are probably more reasons as well.
