I've seen many Android-powered smartwatches out there with capabilities to run apps in the same way (almost) as an ordinary smartphone would. On the other hand, we have the Apple Watch which runs its variant of the iOS system. Imagine being able to install a lightweight wallet like Electrum on a smartwatch to send/receive Bitcoin transactions. After all, most of these (if not all) smartwatches have Wi-Fi capabilities, Bluetooth, and more. By integrating Bitcoin wallets into smartwatches, you can truly send/receive transactions anywhere with ease. I'm sure not if this is possible yet (as I don't own a smartwatch). But if a developer decides to create Bitcoin wallets for smartwatches, I'll be a big hit within the mainstream world.
What are your thoughts? Is something like this practical/secure? Or is it better to continue using smartphones for Bitcoin transactions?

I like the idea of using a smartwatch for crypto transactions but wouldn't the screen too small for this one?
If a smartwatch can connect to the internet alone without your phone I think this is possible.
