You never had the 20 BTC.
No, no

i had 20 BTC, in equivalent value but it was 20 BTC.
DEM Was on Cryptsy when value was 20 BTC so in 5 minutes with these 2 simple operation
1 - Deposit
2 - Sell
My 20 BTC "Dem-Equivalent" would become 20 "real" BTC. I Decided to wait.....and wait......and then it was too late.
It was a mistake, no problem, lesson learned

I don't think DEM will never rise near 20% Of his Max value.
