Hello @project.hope and @crypto.piotr, excellent collaboration, I think it is something really incredible and necessary for other users to be able to exchange STEEM in other crypto-currencies or the other way around, that would allow us to invest both in steemit and in other platforms and still increase the value of the currency if you invest enough in the case of steemit.

Personally I think that the target staff would be the whales, since they move a good amount of STEEM, some small fish would be included too, it all depends on how much they want to invest in other cryptomonies.

If it looks valuable to convert a small amount of STEEM into a large amount and for that I think you should have a fixed rate, because if it varies it can either lose value or go up, but that will be determined by time and community monitoring.

In my opinion, a plus would be that it gives you the option, if you have digital coins and you want to exchange them and invest them to other crypts you can do it from that platform and that in turn you collaborate with developers of the same to continue improving in their work and supporting them to continue with their work.

From my point of view I don't see it as an unfavourable point, rather it opens many possibilities to those who need it and helps other people to expand and make themselves known.

Greetings!
