I do not think that this project will have success in the market in today's reality.There have already been many such ICO trying to inject the blockchain into similar business areas and now look what became with them.No one needs these tokens.
Yes, many projects failed with implementation, because they forgot to do economick model for token. In this project, I think, this is a good prospect, because their current goods are produced with a constant volume and are bought in the store only for tokens. That is, coffee shops will be in constant demand.
