It's a synthetic fiat. Kollider offers options contracts. So by paying $100 BTC to short $100 worth of a BTC/USD "perpetual swap" position at 1:1, you essentially have a (relatively) stable USD. When the BTC/USD value goes up your short position loses value but the BTC goes up at the same rate. At any point in time your position should be worth around $100.

There was a post earlier in the year where Kollider explains these:

This is not without risk, as Kollider is custodian, firstly (not your keys, not your coins), and there's volatility risk -- where either a price spike or a selloff is so brisk where your position is out of balance due to reasons that happen in times of wild volatility, and your short position gets closed. That would be bad.

Or, if Kollider is hacked or otherwise exploited. This would be relevant reading, on that topic:

Also,Kollider is (currently) what StandardSats uses to offer their synthetic stable as well.

https://microlancer.io has been mentioned in Stacker News before, but it still deserves more attention and adoption. KYC-free freelancing for Bitcoin, no ID or bank account required unlike Upwork or Fiverr. Mostly microtasks right now but you can post larger tasks (e.g. "create a website" or "edit a video") or offer your services in the "services" category. Also there is a Telegram group: https://t.me/microlancer_io

Nice. I should get off my butt and figure out how to put some of my old music on wavlake.

10 sats for comment sounds good starting point- I think post should be higher?

I don't think it works like that. Anyone ambitious enough to achieve his or her dreams has another one waiting right around the corner to strive for.
