I already warn about the danger of stableCoin but i came across this good article which mentions some previous attempt of digital token:
- Liberty Reserve (2006-2013) RIP
- GoldAge (1999-2006) RIP
- e-Bullion (2001-2008) RIP
- DigiCash (1994-1998) RIP
- E-gold (1996-2007) RIP
So don t forget there are some risk using Stable coin…
