"Bitcoin dominates the market trend. If you short other altcoins and then target Bitcoin, you're bound to make a profit. How many more people will fall for buying at inflated prices? [blank stare]. The big players, especially from the U.S., are controlling the game and leaving little opportunity for smaller investors."
This idea revolves around the belief that Bitcoin's price movements dictate the overall direction of the crypto market, and that shorting other currencies (expecting their prices to fall) while focusing on Bitcoin could lead to financial gains. The frustration comes from the perception that many investors are buying at high prices, only to suffer losses when the market corrects. The reference to Americans controlling the market suggests that institutional or large investors are heavily influencing the direction of the market, making it difficult for smaller players to succeed.
