A very good breakthrough in blockchain space.
This is a transparent team, and I can recommend that you support the project.
This is a very interesting project, waiting to see it on some serious exchanges

SIDERA.IO is very secure and innovative by using Bitsmart features of smartwatches and smart-bands that focus on Bitcoin and cryptocurrency. The scope of this device is to provide users with an easy, easy, innovative and secure way to manage Crypto-environment.

The most interesting of all features offered are wrist-to-wrist offline transaction and anti-theft system with multi-layer security. In a wrist-to-wrist offline transaction, will the transaction be instantly processed and reach the destination, or wait for online so that the transaction can be confirmed? Then on the anti-theft system, what kind of multi-layer security is embedded, even if the device and private-key are lost or stolen, the account is still secure?

Yes. A project that creates interesting and meaningful things. With Sidera - crypto becomes more familiar and closer to each other. blockchain technology and crypto at their wrists, ensuring that payments are always easy and convenient.

Good, Just a great project. But, for example, I hardly realized that in order to get to the project site, I need to click on the picture. You could add a separate button for this.

Good project and good idea from this project, I see the good progress in the future I think.
I hope this project success
