Newbies should be careful; some people pretend to be customer service/support and direct you to a scam/phishing site.
I had a problem yesterday.
I staked altcoin on a website and wanted to withdraw the coin, but got a problem and stuck to withdraw. I am a bit panicked. Then, I went to the official Discord asking my problem in the general chat.
After a while, someone chat me and admit as customer service, He told me if I have a problem with RPC (while connecting to Metamask).
He directed me to the link to connect Metamask to
rpcdebugger[.]xyz <
this is a scam or phishing site to clean RPC.
At that time, I still wasn't aware, because he acted like customer support. He asked for my wallet address to check my problem, also.
Without suspicion, I went directly to the website and connected it to Metamask, but got an error :

Then I asked him my problem. He told me, if I have connect it manually. I still wasn't aware at that time, and still followed all his instructions.

But, after several steps, I realized that I was being deceived, yes,
that website asked me 12 mnemonic seeds.
Yes, whatever the problem is, there is no one in this world ask you to write a mnemonic seed. If there is, it's fix 100% scam or phishing!.
I must encourage you all here, even in panic, you have to still calm down to always think, and be aware of the situation.
My problem was solved after the real customer support told me that they have a problem with the UI.
