I am active on steem engine and it has been good for me so far. It is a chance for you to get tokens now for a lot of projects instead of waiting for SMT to show up. The serious project can get their tokens right now. Let us own them and sell them in there. Steem Engine will support tokens and other things from all over the place. But it will be connected to steem. This will mean it always should be supporting steem but won't be limited to how steem is doing. Or the changes made to steem. They will run sites with their own rules. With new whales and we will see if any of them can take off and do better than steem. I doubt it but maybe.
