HARLINGEN — So how much is that $20 bill worth?
Not as much as it used to be worth, that’s for sure.
But when it comes to currency, particularly virtual currency like bitcoin, the answer to that question is a bitcoin is worth what everybody agrees its worth.
Bitcoin is at the forefront of a wave of digital cryptocurrencies that are bought, sold and used on the Internet just like cash. Or if not cash, used as you would a debit or credit card to purchase a product.
The rationale for using bitcoin is that the number of bitcoins is limited, so investing in bitcoin is regarded as a hedge against inflation.
Precious metals like gold used to fill that financial niche, but bitcoin is far easier to move and use than physical gold which an investor has in his or her hands.
Bitcoins are produced by a process called “mining.” There is an upper limit of 21 million bitcoins that will ever be mined (hence the hedge against inflation; there’s no government to increase the amount of money in circulation, which lowers the value of a dollar, euro or renminbi).
