There are rounds of fixed time intervals (500 s currently). At the beginning of each round, the bot records the price of BTC
and when round time passes compares the new price with the initial one. Basically you make a bet like "BTC price will go up (or down)",
if you guess you win and get a reward. You need ROCO coins to play. Part of the coins that the users eventually loose will be burned thus decreasing the total supply of ROCO.
By the way, we plan to extend to some other coins but using ROCO will always be more profitable, so this should have a positive impact on the price.
