It is a money-making tool for me at the moment. As long as Dogecoin doesn’t collapse, it’s okay, and Musk has been promoting it, which is likely to become a mainstream digital currency.
I'm afraid you are too much optimistic. Someone who has kept Dogecoin for several years can surely say that it is a joke coin for him. However, if you think this is a good investment for the future, you better play roulette because you will probably have less risk there.
