What projects already exist on the market?
Improving email with cryptocurrency is a very good idea.
At least their idea is unique. For example, I very carefully follow the cryptocurrency market and blockchain projects and meet a similar idea for the first time.
The idea is interesting, but how it will be implemented depends only on the team itself, if they do everything correctly, everything will turn out
I see that this idea can be implemented, and the team works well. but the project needs to have a large community in order for the product to be in demand.
