In the absence of regulations, volatility can be used by unregulated brokers to their advantage and a trader’s disadvantage. For example, assume the intraday bitcoin rate fluctuates from $5,000 to $5,300 U.S. dollars per bitcoin. For an incoming deposit of 2 bitcoins, the unregulated broker may apply the lowest rates to credit the trader $10,000 (2 bitcoins * $5,000 = $10,000).
