In 2013 to 2014, Bitcoin crashed from $1000 to $200
From 2016 to March 2018 Bitcoin was:
$1,000 to $20,000
$20,000 to $6,500
$6500 to to $12,000
$12,000 to $7,500

Bitcoin is the most "feared investment" after going up from $1 to $10,000 in 9 years and big names saying bad things for Bitcoin and cryptos
Bitcoin is definitely very volatile and has not been fully accepted as an investment.
It also hasnt caught on as a form of payment in a mainstream way. Even after 10 years since inception, its safe to say that Bitcoin is still in the early days of acceptance and adoption.
Its going to take some time to catch on just like the way the internet had a learning curve in its early days.
