The "Moonboys" entire investment strategy is based upon convincing themselves and others to join them in their crusade to make their initial investment within an asset class and or security gain popularity in order to gain demand pushing higher valuations so the "Moonboy" can off-load their investment onto new buyers purchasing at much higher prices, as a result, gaining massive profits.
