I am going with DAI.
I'm not really a fan of stable coin considering the scams that have been exposed in that industry. Yet, if I am forced to choose a stable coin I'll go for TrueUSD which is presently 26th in the rankings on Coinmarketcap.
I prefer it because of the integrity of the team involved and its relative stability.
Here is my answer to what is my favorite stablecoin.
My pick is DAI as it is probably the most decentralized stablecoin in the market. Despite Ethereum being down more than 80% since peak, DAI has been serving it's purpose by not deviating too much from USD since it's launch.
In addition, DAI is also the leading stablecoin used in DeFi applications. Lending out your DAI generates generous interest at the range of 8%-20% per annum.
