The service operated normally for the space of 8 days, with an average daily volume of 1.44 BTC. However, on August 2, the company announced the discontinuation of the website:
Dear customers, we are currently reviewing some of our processes and regulatory framework, with the hopes of continuing to provide a legally viable service. We will release further information in the next days. We implore our customers to contact our support department to process all withdrawals.
Colbitex was offering Bitcoin exchange services with local currency (The Colombian Peso COP).

The regulatory revision will establish a legal precedent in the government’s stance on cryptocurrencies.
