Steem Monsters is talking with other crypto communities about adding their coins to SM. This would open doors to other large crypto communities such as Tron and Ethereum.
I am personally looking forward to selling some of my cards for 2x-5x more than I paid for them to some Tron'ie or Eth'onian :)
It's not to late to get into Steem Monsters and start playing.
