Is it an investment platform introduced by online friends (digital currency, foreign exchange and other financial platforms), and the return on investment is much higher than that of normal financial products. In the previous few small investments, the principal and income were successfully withdrawn, but later, the more the investment, the more it could not be withdrawn. You need to pay personal income tax, brush water, fill in the wrong bank card and other reasons to keep you urging money. If so, you may have encountered fraud. Digital currency's transactions violate financial conventions and exchange common sense, and the trading methods are suspected of concealing facts and fraud. To a great extent, it is the reality of online fraud in the name of digital currency trading.
