I like that saying right there. It couldn't be any more true.
I've been in bitcoin since 2013 and I've experienced many crashes, hacks, ponzie schemes, scams and all the sorts.

In 2013 I think, the price of BitCoin got to a high of over $1000, and at that time it was WAYYYY Over prices for where it was. After the crash BitCoin remained (+)(-) $100 form the $200 market. @ a low of $185 during the beginning of like 2015. It was in that time span where lot's happened; going undected the bad kept the price down.

Fast forward til last year, it became popular for once. See back then you would ask someone if they knew about bitcoin, most would say no, and the lucky people that do say yes knew very little about it, or have only heard of bitcoin, and only the bad news that they have on the televisoin news. See they don't post the good development and bitcoins success in the news.
Anyway, to the last year, it gained popularity too fast, which caused this crazy spike to almost $20,000.
No
bitcoin is not worth that. Not even now.
Throughout the years, you'll see more spikes and crashes. But sometimes its a good idea to take a look at the graph from a all time trend of bitcoin.
I see that it's somewhat in a linear line going up. The spikes are big, but you should be able to detect where it should be.
Right now...
My opinion...
I'm no expert
BitCoin will remain under $20,000 until 2020.
