Maker is a digital token created on the Ethereum platform of the Maker project, the primary purpose of which is to create a line of decentralized digital assets that would be tied to the value of real instruments, such as fiat currency, gold, and more. (stablecoins). Dai became the first stablecoin. 1 Dai = $1. However, the MKR, not Dai, is considered the Maker platform's coin. Its holders act as shareholders, which have the highest authority within the system.
MKR coins cannot be mined, so they aren't sold to cover the development costs. That means they will have limited availability on the market.
In 2019, MKR rose from $435.35 to $474.93, a 9% increase.
