Monero seems to be quite unstable. What's wrong with the price?
Actually, it is remarkably stable since start, no large pumps and dumps along the way. Mean average price rising since may.
What is the total range of XMR trading ever, including all outliers?
I gather it should be about 0.00039 - 0.01110. If so, these are only 28x apart from each other

For any other coin, it's more. With Bitcoin, the range is 0.001 - 1,236; difference being 1,236,000x.

I'm interested to know your source for 0.001. Lowest price I've seen documented is 0.003 on Bitcoin Market in April/May 2010 (EDIT: which is the earliest data I have. Do you have earlier, Risto?)
