Interested to know how much of the cryptocurrency coins (count BTC/LTC/PPC etc) that you have mined over lifetime you have sold/spent vs kept in cryptocurrency.  Do not include any coins you have bought, just that you have mined yourself or as part of a pool/consortium.  Dividends or gambling winnings do not count as 'mining'.

Clarifications for the purposes of this poll:

These count as 'selling/spent':

 - exchanged for fiat/national currency
 - buying goods/services
 - gambling losses

Do not count:

 - exchanging to another crypto-currency e.g. LTC
 - Investing BTC somewhere, but kept your investment as BTC (e.g. investing in BTC stock or BTC company) then don't count that as selling/spent.
 - lost/stolen wallets
