The historical charts of LTC/BTC and DOGE/BTC are very similar and I expect good growth from Litecoin!
Also, DOGE is not mined separately by itself. In 2018-2019, due to inefficient mining, in order to keep the network reliable from a 51% attack, DODGE began to mined along with LTC (called merge mining).
The creator of Litecoin, Charlie Lee, publicly got rid (like the creator of DODGE) by selling all his LTC in 2018.
SO THE HISTORY OF THESE COINS IS VERY OVERLAPPING. Also, LTC will soon acquire the anonymity function, and perhaps this will contribute to the impulse growth against the background of the release of various CBDC. Well, in order for the DOGE network to become more secure for a 51% attack, need to pump Litecoin and attract even more miners with this.
