the focus should be on the potential of blockchain technology and how it can improve our world, rather than getting caught up in market manipulation and greed. It's important to keep in mind that the value of a cryptocurrency should not be determined by one individual, but rather by the technology and its ability to provide a useful solution. It's also worth considering diversifying your portfolio and not putting all your eggs in one basket, whether that be Bitcoin or any other coin.
If it's only about potential then Bitcoin has it. BTC has also done some contributions to solve the real word problems like fighting the inflation and restrictions because of its decentralized nature. Doge coin on the other hand is only the opposite of BTC.
I don't know what contributions it did but I think only cause more problems because it encourage people to create more meme coins and like you said to become greedy of chasing easy money. These types of coins can depend on a few powerful individuals because they can be able to manipulate the coin but a legit or fair crypto is truly decentralized and is fairly distributed to all people in the world.
