It is very simple and also risky way to but all are real. If you invest at least 1000 ETH in USDT pair now and hold ETH until the end of 2020 or until it reaches $300 per ETH, you will get 500 ETH profits worth $100000. Isn't it enough to be rich in one year? You can be rich in short period but it has risky too. If invested capital becomes lower day by day and you sell in panic, you will lose your capital. So be practical and do research before invest, select right time and right coin to invest.
