For information indicating an answer to my own question,
my own question, a non-Google search found this Coincentral.com article dated “08 December 2021” (archived 13 Jun 2022 03:01:15);
boldface is in the original, my highlights are added:
Is Celsius Network safe to use?
Yes, Celsius Network is safe for you to use.
The company was founded in 2017 by Alex Mashinsky (CEO) and Daniel Leon (Founding President and COO). Mashinsky is notable for his work bringing cell phone service and free WiFi to the New York City subways, enabling WiFI on U.S. flights, and creating Voice over IP (VoIP). And Leon has had an accomplished career as a social entrepreneur, serving as a leader at several organizations, including Atlis Labs, Beyon3D, and GroundLink.
To date, Celsius Network supports over 101,000 users worldwide containing over $730 million in assets. Additionally, the platform has facilitated nearly $5.5 billion in loan originations (about $8.2 billion in today’s BTC prices). The company has made $12 million in interest payments,
You should note, however, that Celsius Network is a custodial wallet platform. So, the company keeps control of the keys for each of your cryptocurrency wallets. While this fact shouldn’t be a deal-breaker for most people, it is essential to know.
By the way, does Coincentral.com have a forum account against which a Type-1 flag can be raised? Spreading the highlighted type of misinformation causes newbies a high risk of losing money.
Further down, the same article provides this warning about that assuredly “safe” custodial platform, where
trust-us “shouldn’t” be a deal-breaker:
An important warning: Currently, Celsius Network does not provide any insurance on your deposits. So if the company falls victim to a hack, for instance, there is a possibility that you will lose your funds.
Anyway... For a back-of-the-envelope guesstimate of the magnitude of a Celsius collapse: Allowing that it’s likely that Celsius exposed assets shrank between December and June, it looks like this is probably one order magnitude smaller than the Terra collapse—which, in turn, was about an order of magnitude smaller than Gox in terms of BTC lost (Gox) or dumped (LFG), but two orders of magnitude larger than Gox in dollar terms of total losses.
IMO, that would barely cause a blip in the BTC price chart—if the market were not already beaten to hell by Fed interest rate news, Terra, massive FUD, what must be
terrifically huge and professional organized shorting, ridiculous coupling to a crashing stock market,
and the mass-reaction to the latest official USD inflation numbers. If Celsius is the cause of the current rapid downswing, then it is the straw that broke the camel’s back.
Edit: Corrected order-of-magnitude comparison of the Mt. Gox collapse to the Terra collapse, in the penultimate paragraph.
Archive of original. Cause of error: Brain malfunction; I
know the relevant information. I dislike making such a substantive alteration when a post has already received merit; but the numbers I stated were factually wrong, and a misstatement of order-of-magnitude is not insignificant.
