So let's analyze the latest cryptocurrency spammers and see whether they can even tell us a legitimate story about their miracles, which I have yet to find one that I believe is bona fide.
This is yet another lazy story that sounds like it's fabricated as it starts immediately by telling you about scammers without providing any background as you'd expect from someone who was actually a victim of a cryptocurrency scam. Of course there are no details about what cryptocurrency platform the alleged scam took place upon but it involved liquidity mining for stablecoins known as Tether? The allegation is that the theft of Tether is untraceable and there is nothing that can be done about it. Read the following article, which explains the difference between cryptocurrency like Bitcoin or Monero and a centralized stablecoin like Tether. This is a lazy attempt at a testimonial that doesn't work.
Tether Freezes $500 Million in Assets Linked to Turkish Gambling Ring
They use terms like "blockchain forensics" which is general enough to impress the common person. Then they talk about clustered wallets - with no explanation as to how they were able to trace a process that is extremely difficult or not feasible to track. But miraculously, of course, they recovered the stolen crypto from these wallets into the victim's wallet - and there is no one able to corroborate this miracle.
I looked at Whsipers Hacker Recovery website and couldn't find any actual names associated with this service. The website uses some fancy technical terms about one case study and essentially confirmed what I have repeatedly stated - chances are extremely high you will never recover your funds. They did identify some accounts (wallet addresses) that were used and held funds, which many with some level of knowledge of blockchain technology can do using "block explorers" which are publicly available. They also identified "recovery channels" - which means the ability to try to recover funds, but it doesn't state that the funds were actually recovered. If you were lucky enough to have a hacker use a regulated centralized exchange to park money, such as Tether, you might be able to recover funds or at least freeze some of them. But what's the chance that will happen? Probably next to none. So before you advance money to any "recovery service", understand that chances are usually very good that you'll be throwing out good money after what is long gone. Even if an account or "wallet address" is identified, on virtually all public blockchains at present, there isn't any authority that can freeze the funds or force a return of funds to your wallet.
Beware of crypto recovery services and also of requests for fees and expenses in advance.
