looks like what you said is true. maybe some people think that the mysterious coin that suddenly entered the wallet list is a threat.
I'm still confused until now, this is happening on local exchange/CEX.. like a mysterious increase in the balance of some of my tokens, I don't know if this is also what you mean? and is it dangerous or safe?
No, we are not talking about tokens being sent to exchanges, for those tokens to be sent to exchanges, they should have been previously listed, and they are not. We are talking about tokens that appear in our wallets without knowing why, and for your information, no, they are not safe, they are scams that want us to interact with their smart contracts (send them for example), that way the attackers could steal our funds.
There are many, but some of the best known are:
• LUNA-Swap
• Milkyswap
• OrbitDefi
• TheVera
• UsdSwap
There are more, many more. Be careful!
