Tether and stable coins
Stable coins, so named because they are 'tied' to something, typically the US$ or other currency.
So when Tether changes it's web and seems to indicate that while its coins are 1:1 with the US$, they may not be backed by actual dollars any longer.
Initially this may seem strange, but there may be at least 2 possible reasons.
Tether is having liquidity issues, and has to call on other investments, without selling them, in order to balance the books and cover the issued value of its coins.
Having all your eggs in one basket may not be such a great idea.
What if the US dollar devalues? What if the stock market crashed?
So much could happen in money circles, perhaps having the value of a coin tied to just one thing might not be a great idea for future longevity.
Time will tell
