The fact is that in 2016, the cryptocurrency market showed quite large opportunities that people wanted to take advantage of, but the results of their activities turned out to be far from what was expected.
2016 gives opportunity because the price is lower, I think it's just like the current situation, the sad thing is that we were dump that's why we are here.
The last bull run happened in 2017 and price in 2016 if I still remember right was less $1,000 and if people are buying that time, they could have at least x20 of their initial capital if they sold during the ATH.
Today, for many users, cryptocurrency and losses are much higher than revenues.
Because they are not smart, they maybe dump that's why they loss.
