Unlike
traditional fiat currency where money can be printed over and over, Bitcoin has a controlled and predetermined supply, making bitcoins scarce, similar to the properties of gold.
Tether Limited has designed
currencies that act as anchors or «tethers» to
fiat currencies like the US dollar or the euro,
where every tethered cryptocurrency issued in circulation is backed by a 1:1 ratio with
traditional currencies held in deposit by Tether Limited.
