Investment ? NOT ! Doge is not a coin that was created to invest, doge was created only for a mere entertainment not more, even if you intend to invest there I am sure you will not get a good profit
Many times doge have been pumped to more than 100 sats and i believe if there are lot of people who become rich when that happened. Created for entertaiment only or not, DOGE still alive until now since 2013 and on the top 30 coin too.
