The price of bitcoin rose above 19,000 dollars (almost 16,000 euros) on Tuesday for the first time in almost three years.
The virtual currency has been on the rise for some time.
At its highest level so far, 1 bitcoin equaled $ 19,666.
This year, the crypto coin has appreciated 160 percent.
In this month alone, the coin has already increased in value by 40 percent.
Bitcoin's advance is partly due to the fact that virtual coins have acquired a kind of adult status and seem to be here to stay.
At the same time, the measures whereby money is pumped into the economy cause a depreciation (inflation) of traditional money.
In the twelve years that bitcoin has now been around, the price has proved to be very volatile. There are investors who think the value could be as high as $ 100,000, skeptics argue that the virtual currency is purely a speculative investment.
