I was just looking into storing my money on the steemit blockchain. I see interest payments on accounts that do and it looks very nice indeed. I agree with everything you are saying. But
But.... I live in a country where the paper has collapsed and prices on everyday things is $2-$4 higher every time you go to the supermarket for the last 2 years. Milk has gone from $0.80 to over $29.00. The dollar has done the SAME (but over a 50 year period) eg; the same loaf of bread was $0.29 in 1980 and look at it now.
When the dollar collapses, I would rather not have a hard peg (or at least an instant way of pulling out from the pegged asset). That is why I have ALL my money in either gold, silver, btc, eth, dash, or steem.
