I think you read my massage not right. Read it again...
Your message was:
Exchanges 21000 XPR for 4BTC
There's so such thing as "
XPR", as far as I know. The closest thing I know is "ripples", which has the symbol "
XRP". Note the 'R' comes
before the 'P'.
So you either made a typo, or there's some new alt-coin that has symbol "XPR". ('R' comes
after 'P')
