A lot of the average joes got into this for immediate profits, noy long-term investments with a high degree of risk.
For example, mining in 2011 and then cashing in Jan 2018. Not riding the carousel of buying BTC for 10K and seeing it now at 6K and getting desperate that it might never recover.
If you were lucky, you were lucky, and if you didn't dump when it was obviously profitable, than you're regretting now 100%. I did dump in December 2017 and I'm never touching this again.
