Exchange course: 1 Crystal = 10 Satoshis
You can claim your crystals each 60 seconds or
choice the best time to claim them.
The crystals will gradually fill up - quite quickly initially but it will slow down
over time - until you make a claim or reach maximum capacity.
If you want to earn even more, you can use your balance or
invest some satoshis to create new crystals.
