I As for me, the main advantage is ability for masternodes creations and multiply funds.

Medicohealth is not about that. It is about getting treatment when someone needs it

Maybe bankera is a slow project because this is a banking project with legal barriers, but I think bankera's team has really wise reasons behind:
1. 2018 is a disastrous year, so bankera may have limited development strategies to maximize budget while market conditions are extremely bad. So far I consider it a wise decision: to reserve the project budget until there are positive conditions.
2. While waiting for the market, bankera's team has a lot of time to take care of their products in the future, making sure they get the best quality when it comes to users.
3. bankera is supported by spectrocoin's experience, potential and credibility, so bankera will soon develop when good conditions take place.
4. Until now, bankera has been concentrating on keeping the project progress and still developing the next items.
Currently, it can be said that the market is entering a period of growth again, I believe that bankera will soon, very soon will launch its core strategic products, and will open marketing campaigns, joint a large-scale project to bring bnakera into a pioneering project in the banking sector. I still keep my trust in the project.
