Thanks for your comments: I incorporated several suggestions. I think that the usefulness of this announcement decays with every passing hour, so I went ahead and posted it. I'll also link to it in the news bar for a couple of weeks. The post can still be edited, of course.
Has anyone used the Unstoppable wallet? Is it a good alternative to Trust Wallet?
I partially agree... I will fully agree if title is changed to..
"Get your funds bitcoins out of exchanges"
or
Title: Withdraw your crypto bitcoin from online accounts now!
"Withdraw now" strikes me as a bit too alarmist, and I prefer the term "online account". "Exchange" is too narrow, while trying to be more exact with a phrase like "centralized exchanges, yield sites, and many tokens" is too confusing.
Note that even USD in exchanges is at risk, whether or not it's a stablecoin or a non-stablecoin account balance. If the exchange goes bankrupt, typically the USD will be an unsecured liability owed to you by the exchange, the same as any other asset associated with your account.
But we should warn them to avoid "yield" platforms that promise you a percentage APR because these platforms are inherently unstable.
I agree that yield-farming stuff (whether DeFi or CeFi) is very risky in general, and especially right now when $2-10 billion in "money" was just removed from the crypto economy overnight. I adjusted the wording to emphasize that yield products are included. "Inherently unstable" goes a bit too far, though, IMO. For example, some decentralized exchanges and over-collateralized lending pools seem pretty robust at least in principle, and many of them will probably survive.
I would not like officially the forum to mention such wallet names which have business associated with it. You are giving them an advantage from others that are in the market. On the other hand when something will go wrong with any of them mentioned then people will have scope to say they were recommended by bitcointalk forum. We do not want to take any responsibility of anything.
I don't consider it to be an issue. Those clearly are the two leading hardware wallet manufacturers, and merely mentioning them is not an endorsement.
