The latter currency is taking away gradually, which can explain the demand for Bitcoin. Cubans citizens are seeking to get more steady cash to win over the economic crisis. Cubans are facing difficulties in gaining hard money – coins or paper cash. Traders also have hard times as a liquidity crunch has affected usual operations. Banks and big financial enterprises have no cash to give loans to traders. Even daily things and services are difficult to purchase.
