Only 66 stablecoins — 30% of total announced tokens — are actually live and operational, according to a study published by the blockchain research group Blockdata on June 26

The remaining 70% are either still in development or have shut down entirely.

Researchers from Blockdata believe that one consequence of this is that 2019–2020 may see a record high of new stablecoins going live, with 119 estimated to launch in 2019.

Researchers also examined possible factors may have led to the closure of failed stablecoins. Failed stablecoins, according to the study, tend to be commodity-backed by assets such as gold. Gold-backed stablecoins, in particular, accounted for approximately two thirds of all failed stablecoins.

Looking closer at the failed, currency-backed stablecoins, the researchers found several factors that they deemed to be responsible, falling into the categories of volatility, physical storage complications, and scams.

Some other trends noted in the study included the prevalence of Ethereum-based stablecoins, as well as asset-backed stablecoins. While the report identifies 15 different blockchains that stablecoins are implemented upon, Ethereum retains approximately a 50% share of all stablecoins by blockchain — the next most common being Bitshares and Stellar.

Asset-backed stablecoins also comprise an overwhelming majority of all live stablecoins, at 95%. While this remains the most common means of stablecoin issuance, algorithmic stabilization and other methods can be used to develop a stablecoin.

As previously reported by Cointelegraph, Steve Forbes, the namesake of business publication giant Forbes, recently told Mark Zuckerberg to back Facebook’s stablecoin-like virtual currency Libra with gold.

Forbes believes that gold will provide fixed value for the upcoming virtual currency given the precious metal’s purported history of stability:
