I have a friend who has known the crypto market since 2014. He is quite poor at that time because he is a student. In 2016, he decided to invest more than $ 1,000 from borrowing friends on ETH and holding it up until the end of Q3 of 2017. He raised his amount to $ 406k. In addition, the government in my country has not collected taxes from the money-making market in decentralized markets. He has all and been rich since then.
