As the value of the currency increases, doesn't that make actually using the service prohibitively expensive?
Also, the Sia wallet has been completely inoperable for about a week, which is what has caused its latest price inflation. It went from .02 to .10 so I figured I'd get rid of it, but I can not send it from my personal Sia wallet to an exchange.
The recent issues have been on exchange wallets, which should be fixed very shortly on Bittrex and Shapeshift, as announced recently on Reddit and Twitter.
AFAIK this is an unsolved problem for all "app coins"/"utility tokens"/"fat protocols". The service could be dynamically repriced when the value of the currency changes, but that requires oracles and many cryptocurrency idealists are reluctant to admit that things should be priced in a stable currency.
I personally have not had issues moving siacoins, but a few exchanges have been slow to patch issues on their end in the last month: https://www.reddit.com/r/siacoin/comments/7pc5rv/brief_offic...
