About link description

Introduced in 2018, the KaratGold Coin (KBC) is reportedly linked to physically deposited gold in the form of CashGold, a gold standard. KBC was created by the KaratGold Coop to address the inefficiencies and fragmentation of the existing payment system. Karatgold (KBC), together with the KaratGold Ecosystem, believes that it has developed a globally workable solution that is connected to gold.
