Most of the holders have had the same experience and are like 80% down from the ATH. When I started in this space I would go mental in this kind o situation but now after surviving couple of dips of this nature I have a very phlegmatic mindset about it.
You can think of it as a sort of "good" introduction to Bitcoin and cryptocurrencies. I know for me I was introduced around the time when the first "major pump" to 1K started in 2013 after sort of hearing about it before through other forums. I freaked out at first when my investment at first started to dwindle and after doing more due diligence I started to realize and understand some of the fundamentals about Bitcoin and bockchain... hopefully other people who got brought in from the 2017 hype will start to do their due diligence now as well.
