DolarToday is awesome an interesting way, it publishes what is Cucuta exchange rate for Bolivar, which is taking a drubbing and gives a wonderful insight into the economic meltdown that is taking place in Venezuela for the past 2 -3 years. What Chavista politics/Socialism can do to a country.
The official exchange rate is 1 USD = 6.3 Bolivar but Cucuta rate is 1 USD = 820 Bolivar. Venezuela is basically trying to muzzle dolartoday, because there is impending election in December where Maduro et al. will like be facing a drubbing. So, the powers to be in Venezuela are doing everything possible, including shutting down this site, so that they can project both inside and outside that everything is hunky dory.
Venezuela is a cautionary tale of Latin Socialism.
