Whats the ROI for staking and is there a minimum number of coins reqd? Also ,how often does it stake ?
You can calculate your rewards ROI as follows:
T is the total number of COLX currently staked, currently 5.99B.
P is your personal number of COLX staked.
1440 is the number of blocks in a day.
T / (1440 * P) = Your average number of days per reward
