The dollar blue is a highly speculative type of exchange rate. It moves quite a small amount of money daily and it's linked to just a few large moneymakers in the City that oftentimes have their own agenda at setting up the daily rate. CCL/MEP are much better proxies for the value of the dollar even though these rates are also quite volatile at times, and also subject to manipulation by some players, but certainly a much better indicator than the blue rate.Is there any company use Blue?
