Here is why its worth the $$, there is a little phone app on it called Price Drivers, now start bidding it up.
I know lots of traders who are begging for $$$. LOL. I'll offer $25.75 for this. If you're such a successful trader why not donate the phone? A measly $2500 contribution is peanuts to a successful trader. I donate $5K to $7.5K per year to local high poverty schools and don't think twice about it. Or is it that maybe you really don't make much $$ as a trader?
These seem to be going sub $1000 on ebay. Now if it was previously owned by a trading god like say PTJ, it would be worth $2.5K+. However it is owned by a struggling (and probably broke) trader, so means this tainted example (comes with current owners bad luck in making market calls) is worth less than market price, i would say $250 at most.
Do you remember the colorful lady governor from Texas? If she were alive today then I'm sure that she might say,"Poor Marketsurfer, he was born with a silver foot in his mouth".
