I think stack still needs to deliver on the promises and the products that were promised during the ico or may be the project team is intentionally delaying development due to bad market conditions, i know stk is lacking volume and value in the market but that can be improved only by providing real solid products as promised.

Non fungible tokens are really innovative. I don't know though how reputation is going to be increased if more users join the platform. Would the supply increase after a specific amount of registrations?

Any distributed p2p, digital currency which relies on trust to make it work is nothing more than a horrible mistake a best, and at worst it's a scam.

As soon as you make that trust sacrifice, you might as well throw it all in the bin and use VISA, which has none of the drawbacks associated with crypto, and is already accepted everywhere.

If you want an authority, why do you need a blockchain?  Do you see a particular usecase that blockchain solves in a situation where you are fine with a trusted authority anyway?  In my opinion, a blockchain would just be a very inefficient database and/or buzzword in such a situation.
