If you will take crypto investment and trading as a gambling game, you will lose for sure. It is not a game. It is a serious business. And entering this market you should be able to control yourself, your emotions, your bankroll. And the most important thing is that you shouldn't join this market without the necessary set of knowledge of it, of its behavior. Otherwise, you will soon lose all your investment. It is not true that only Bitcoin is worth something. There are a lot of good cryptocurrencies out there, because behind each of them is a working product and company (like behind stock exchange shares). But everybody picks its own investment coins. Before investing, learn this market, its coins, and the platforms/products behind them. You can make profit (even a big one) on any coin you wish but only if you have the necessary knowledge of this market, trading and the right time to buy and sell. But that knowledge won't come without the actual experience. If you here to gamble, better leave now if you don't want to lose everything. This market doesn't spare amateurs and unprepared people.
