The California Department of Financial Protection and Innovation (DFPI) issued warnings in two days against 17 cryptocurrency brokerage firms and websites it suspects of fraud, saying the firms "appear to be defrauding California consumers," including Tahoe Digital Exchange, TeleTrade Options, Tony Alin Trading Firm, etc. In addition, there are two copycat websites pretending to be eth-Wintermute.net and UniSwap LLC. DFPI urges consumers to exercise extreme caution before responding to any solicitation to provide investment or financial services, and to check that investment or financial service providers are licensed in California.
