Let me tell you a story of success: I bought 2 r9 290x and 1 r9 280x and with these 3 video cards I have made $25,000 USD in a matter of a few months. I just sold all of my drk at .026 but im rebuying in soon.
EDIT: people I have introduced to crypto who see how successful I am always ask me when they should buy or sell. if you ask these questions you don't have the intuition for this
