After the fall of the Bitcoin movement, how will the Stablecoin movement with Libra and Gram play out?

Will the Stablecoin movement succeed where Bitcoin failed?

The cryptocurrency movement that was started by Satoshi Nakamoto at the end of the global financial crisis in 2008 focused on Bitcoin and its transport mechanism Blockchain. But Bitcoin had an Achilles heel which was that the currency wasn't tied to any established currency and so came to fluctuate almost as much as the Deutschmark in Weimar Germany at the end of the 1920s.

But it is also possible to create a digital currency and tie it to an established non-digit currency, a s.c. Stablecoin. Which give you a digital currency without all the fluctuations of a Bitcoin-type cryptocurrency.

And maybe that is the way forward for the future of cryptocurrencies.
