Most stablecoins already need a third party to keep the price constant, so I do not think this news will create any difficulties for their users. The project owners will be obliged to work more accurately, which in my view means more reliable coins. The only problem may be for decentralized stablecoins such as DAI, with their centralization they will almost be destroyed.
That's certainly true, mate. The real deal will be with so called "decentralized stablecoins" like DAI and bitUSD. They largely depend on algorithms than a third party to maintain their prices of $1 USD per coin. I wonder how governments will be able to regulate these stablecoins too? The pressure from Facebook's stablecoin named "Libra", has urged governments to regulate the industry. They're mostly afraid that these digital assets will replace traditional Fiat currencies within the mainstream world. For cryptocurrencies like Bitcoin and Ethereum, that's another story since they're largely volatile in price. Most governments don't care about these cryptocurrencies because of this factor. But expect stablecoins to be heavily regulated as they prove to be a better alternative than traditional Fiat currencies of today.
Nonetheless, time will us what will be the implications of stablecoin regulation within the crypto/Blockchain industry. If governments will be able to successful regulate stablecoins, then I believe we'll be able to see serious investors joining the industry. Otherwise, the crypto market won't be able grow into a massive user base because of the dreaded volatility inherent within every cryptocurrency across cyberspace. For the end user, stablecoin regulation shouldn't be a problem. But for businesses, and companies offering such solutions to their customers, this might be more of a headache than anything else. Just my opinion
