It’s a line we’ve likely heard in various westerns, and yet it’s probably something bitcoin has said at least once or twice to its newly developing crypto-cousins. No doubt that six years ago, when bitcoin was just starting out, it was ready to take the digital world by storm as the only currency of its kind. Over time, however, bitcoin’s territory was being invaded. Dogecoin, Litecoin, Darkcoin, they just kept coming, and they simply haven’t stopped. It appears as though every week a new digital coin is emerging from the shadows, ready to declare war and claim bitcoin’s turf as its own. Bitcoin suddenly began realizing that while it may have been the first, it certainly wouldn’t be the last, and the cryptocurrency space was growing to accommodate everything making its way onto the scene. “This town ain’t big enough for the two of us” later became, “This town is getting bigger for all of us.”
