If someone knew the answer to this question, I doubt they would stick around trying to answer this question in this forum. They would be partying like crazy into the night. The truth is that no one can say for sure which altcoin will make you rich op. Luck and smart thinking play a big role in determining if you will become rich or not. Do your research and pick the coin which you feel will blow up in the future. For me, it is Stellar Lumens all the way.
