It’s STELLAR LUMENS (XLM), a payment solution on a blockchain, similar to Ripple. They were doing give-away of free Lumens to everyone holding Bitcoin two months ago (see the original post I linked to in the first paragraph of the post above). That’s how I unexpectedly ended up with a whole bunch of them. But they have been getting increasingly less valuable ever since, that’s why I finally pulled the trigger and got out of XLM.

I now get it ,thanks for explaining
