No, should I?

Also, if it is a scam, is there anything that can be done to get it shut down at the very least? Where can I report it? Would legal action bring any sort of results?

I made an account after seeing some advertisement on a Discord server about sign-up bonuses, but now they're asking for an additional deposit of at least 0.01 BTC for "external wallet verification."

I know that is not necessarily a red flag, lots of exchanges, especially European ones, ask for this as Proof-Of-Ownership, but the amounts are usually much smaller.

I made my account here just to ask about this because I'm really hoping I haven't been scammed.
