But during 2019 there were merely a handful of people who would say with real confidence that Bitcoin will surge to six digits. Many times, those people were derided as stupid, or called "Moon Boys". ¯\_(ツ)_/¯
The same is true in 2015 and 2016 (the year of your forum registration) Many folks probably considered $3k to $5k to be the top for the next few years, but we had a bit of an overshoot in 2017 to the upside and then to the downside correction that did not even come close to as low as the BTC price had been in 2015 and 2016...
I would absolutely be one of those people who never have believed that Bitcoin would surge to $20,000 OR even five digits. Hahaha. But it was only during that time, that it started to become obvious that six digits is a possibility for the next cycles. Although there were many people that remained very doubtful.
Many doesn't expect that to happen since $20,000 big at that time and many doubt that it will be so hard for bitcoin to pump on that amount or more bigger than these since many are afraid for the possible dump to happen.
But for so many times it proves us that if we keep doubting there's nothing to gain and we regret our decision for not buying while bitcoin is quiet affordable. For sure we think about going to past where everything is cheap that's why people should not make the same mistake again since there's still plenty of time for them to accumulate and they should not about they came late since on bitcoin there's nothing like that exist since price of bitcoin continuous to grow.
