There was a new update from steemmonsters yesterday.
It is a DEC token. The DEC token is a token issued to the STEEM engine.
In a ranked game, you are awarded a DEC token for as little as three or as many as twenty.
After playing for a few hours yesterday, I received about 300 DECs and earned about 0.5 STEEM.
Today, DEC seems to be getting smaller.
I think a lot of people are expecting more STEEMMONSTERS games, so the value of DEC can go up.
