The dot com bubble started around '95, so about 4 years before the bubble 'burst'. YT is damn near 20 years old. BTC is 13 years old. What is similar?
Lol no the dot-com bubble didn't start in '95. It started in 98/99. YT and BTC haven't been in a bubble since they were created. Bubbles usually don't start when something is created, it's when there's a mania FOMO component among ordinary people. I've researched bubbles since the 1700s.
