Looking at performance retroactively is flawed. To highlight the problem, Dogecoin gained +2500% in the past 3 years despite being created as a joke. Naming past dates where something had big gains does not retroactively make it a good investment.

The live Dogecoin price today is $0.1897 USD with a 24-hour trading volume of $1,948,044,919.70 USD. We update our DOGE to USD price in real-time.

I recommend calculating how many years of data someone provides in their examples. The above example uses 21.3 years (2001 - now), which is an odd number of years to pick. When you see that, suspect someone has cherry picked the start date to make their asset look better. By the way, 2001 was the first full year of the dot-com crash, which is also a suspicious starting point.

Consider a more neutral 30 year period from 1993 until 2022, using Portfolio Visualizer to run the calculations :
