Hello! I am new to cryptocurrency and for me this topic is not yet fully known. I would like to know something.

Recently, on Bitcointalk, I found a topic in which a person wrote about one channel in telegrams, they sell bitcoin wallets with a balance at a price much lower. Has anyone already bought such wallets? I spoke personally with the seller, he provided me with a lot of evidence that they work honestly and they really have wallets. But still interesting, maybe someone else worked with them and knows this telegram channel. I would be grateful for the information.
Here is the link to the channel: t.me/engcryptoshop
If anyone has any information then let me know. I will be grateful. thanks
