Magma.amboss.tech is it real

Hi, totally new to this world. I bought a start9 device, but never used it for lack of a clear aim. So it is still in the box since a few months.

Now I found on X about this magma.amboss.tech thing that seems to provide a yield on BTC without releasing the keys, but you have to keep a node. Also this seems to be in exchange for liquidity. Hard to understand!

OK, that may be a reason to find the time to take my start9 out of the box and install it.

But is this possibly true? How may somebody give me a yield on my BTC if I keep the keys and I am the only one with power to use these BTC?

Well, if you confirm that it is really possible and I may trust this Magma-Amboss, then how to set up such a node? Is there an easy guide?

If you think I am too ignorant and with no time to try something like that, you may suggest to keep the start9 in the box, no problem whatsoever.

But if you think there is an easy and fast way to get it working and perhaps you are willing to guide me for a fee, that would be encouraging.

Best

I’m not sure how outdated this now is. Three years is an eternity in this space. But it might be good for some foundational knowledge.
