A court in Florida has ruled police can arrest an individual who sold Bitcoin Core (BTC) to an undercover officer in a sting operation, in a judgement expected to make it easier to prosecute unregulated cryptocurrency transactions in future. Police in Miami Beach tempted the defendant, Michell Espinoza, to sell BTC in an unregulated deal, presenting \u2018smoking gun\u2019 evidence for prosecution. In court, Espinoza argued that BTC was not considered money under Florida law. The charges relate to an amount equivalent to $1,500, from which Espinoza netted around $83. The Third District Court of Appeal overturned the decision of the previous case, finding that the judge was wrong to dismiss felony charges brought against Espinoza when he likened BTC to \u201cpoker chips that people are willing to buy from you.\u201d The judge held that as a form of money transmission, Espinoza should have been held liable, because he should have been registered with the appropriate agency, the Office of Financial Regulation. Describing Espinoza\u2019s enterprise as a \u201cbusiness,\u201d the judge said there was a requirement to register as a payment instrument seller and money transmitter. According to the ruling, \u201cEspinoza\u2019s bitcoins-for-cash business requires him to register as a payment instrument seller and money transmitter...not merely selling his own personal bitcoins, he was marketing a business.\u201d Professor of economics at Barry University, Charles Evans, said this was reflective of the increasing confidence of law enforcement in cryptocurrency cases. He was quoted by the Miami Herald as saying, \u201cThe Wild West days are over. The regulators and prosecutors are trying to bring order to all the chaos \u2014 and this is part of the process.\u201d The judgement is particularly significant because it sets a precedent for future cases, effectively authorizing police to bring charges against those found to be engaging in unregulated transactions. It comes at a time of increasing law enforcement efforts, designed to tighten up restrictions around cryptocurrency trading and exchange. With cryptocurrency still in a legal grey area in Florida and other states, the case highlights the ongoing need for more defined regulation, specifically dealing with BTC and other cryptocurrency transactions.
