Some good comparisons there OP. Compared to some of the other altcoins, Dogecoin actually hasn't done too bad in the past 2 year period.
Dogecoin November 1, 2018 High- $0.004 USD
Dogecoin November 1, 2020 High- $0.0029 USD

Personally I feel that anything other than a very short term investment with altcoins is highly risky. Most altcoins are very influenced and affected by Pump & Dump schemes and unless you are able to watch the market for your altcoin holdings nearly 24/7 you are likely to miss out on the highs and lows. For instance you could be away from your phone/computer for 24 hours and have missed your altcoin catapulting to its All-time High and then dropping down to its All-time Low shortly after once all of the big traders/holders dump their coins.
