Hi there. This is how the staking system is designed to work. The initial bonus KWT doesn't expire after 90 days anymore, as announced recently by Vali. However the initial .11 KWT for each staked MWAT is available for a period of one week, pre-announced so everyone can prepare for it.
I cnt understand. What will be with this KWT bonus tokens after? How will we can use this KWT token? Is this token will be trading on some exchanges or just on your platform? And who will be interesting in buying this tokens?
