I used to mine Doge like crazy because I liked the big numbers. The profits were scarce.
After some time, the pool I was mining with turned into a pool with some service of cloud mining for Doge.
Stupid me invested in it and after one month the site was closed. I got scammed and gave up on it.
Damn.. I've heard about others having problems also. Sorry that happened bro. More profits to be made with so many other coins though but that sucks.
It was a lesson. And I got so many lessons after that it's unreal. I am a slow learner apparently... Maybe this year I am ready for my final exam... The result will be available for me at the end of this year, you get the point :D
