You bring up good points, but look at USAS chart at $3.58. $1800/sh in ’04 adjusted for a 12 for one reverse split on 12/28/16, meaning that stock was .29 cents. $3.58 gives it some respect and a new start.

Re your “it (the dollar) goes down probably to where it was before” Yes of course, but if it’s already too low in value, they have to get the value higher again for new ride down in value. Can’t go from low to zero.
