There are 3 distinct tokens, Steem, Steem Power, and Steem Dollars
Steem is not based on nor backed by the US dollar. Likewise Steem Power also is not backed by USD. Steem Dollars however are pegged to USD and 1 Steem Dollar should always be more or less equivalent to 1 USD. So in a scenario where the US Dollar loses all its purchasing power, you can expect the Steem Dollar to do the same. Steem and Steem Power would not be effected.
Ok. Thank you so much for your reply. I'm still trying to understand this. One more question please. If the dollar collapses will you be able to purchase goods with Steem and Steem Power?
When you power down you Steem Power, you get 104 weeks of what? Is that United States dollars or is it something else?
