From time to time, Bitcoin is surrounded by controversy. Sometimes it is linked to its potential for
becoming a suitable monetary alternative for drug dealing and money laundering, as a result of the
high degree of anonymity.9 On other occasions, users have claimed to have suffered a substantial
theft of Bitcoins through a Trojan that gained access to their computer.10 The Electronic Frontier
Foundation, which is an organisation that seeks to defend freedom in the digital world, decided not
to accept donations in Bitcoins anymore. Among the reasons given, they considered that “Bitcoin
raises untested legal concerns related to securities law, the Stamp Payment Act, tax evasion,
consumer protection and money laundering, among others”.
However, practically identical problems can also occur when using cash, thus Bitcoin can be
considered to be another variety of cash, i.e. digital cash. Cash can be used for drug dealing and
money laundering too; cash can also be stolen, not from a digital wallet, but from a physical one; and
cash can also be used for tax evasion purposes. The question is not so much related to the format of
money as such (physical or digital), but rather to the use people make of it. Nevertheless, if the use of
digital money in itself complicates investigations and law enforcement, special requirements may be
needed. Therefore, the real dimension of all these controversies still needs to be further analysed.
