Remember when we used to be told that crypto is untraceable, unhackable, that means people can do things on it anonymously and get away with anything. Well, that created a breeding environment for criminals and allowed them operate how they like. In the past, criminals could get away with anything, kidnappers could demand for Bitcoin or whatever cryptocurrencies as payment and get away with it. People that participate in the Dark web trading did the same thing. But recently the case has been different as wallets get tagged with marks that makes them identified as dangerous wallets.

A lot of wallets gets flagged as dangerous wallets or being flagged for suspicious because of what they must have done, like scamming, so most times they don’t want to use Centralized Exchanges to withdraw their money, so they rather use crypto vendors for that. Lots of people earn money from being a crypto vendor, they help people trade their crypto, which is very risky because accepting a coin from a suspicious wallet could flag your wallet also. So to be safe, you have to use certain tools to know the safety of a wallet address.
It’s advisable to look for crypto wallet checker sites to know the risk health of these wallet addresses before transacting with them, always try to be careful so you don’t fall victim. I am not going to share any website for safety reasons, but I will advise you do your own research.
