Thomas,

the first 1,000 HP will be used for mining crypto's, that's right
but ALL HP , also the first 1,000 will also be used for CGT

You have some 12,000 !!! (level 21-22)

I have at this moment 13036.47913896  HPower (almost level 20)
I save those CGT ...(5.192009117573 CGT) as you mentioned when you buy cards from CGT into the shop it will be worth 1/100e from mining crypto's

I still have some hope Jamboom will change those prices more to what the average price is into the market, those fixed prices in the shop are up to 23x as much as the average prices members use into the market.
