Doge has some necessary features to be successful going forward. If you accept that then it may be a good idea to invest a few bucks, especially, as Doge is, so to say, a penny crypto coin. The upside can be very significant while your loss is strictly limited by the sum that it is not big pain to loose.
I think it does not worth investment, but like a joke, its price went up like crazy. Some whales will be much richer, it seems. Amateurs are getting fooled by that high price and they're buying. Unbelivable.
