I'm interested in how you can stabilize the price of a coin, if it is based on a decentralized system?
A coin will stabilize even if it is based on a decentralized system when it is constantly being used for buying and selling at the same time with balance. I think there are some coins out there that are good to accept as payment since they rarely moves. Although that is the case, a true stable coin which does not fluctuate at all isn't decentralized but it would surely be a centralized one because volatility is always there on the free market.
