I agree, scammers are very much in the cryptocurrency ,
Scammers exist in every sphere of life and not only in cryptocurrency. You get mugged in a dark alley, scammed on your credit card with false promises and scammed by the pavement beggar who is making a fortune begging. Do you complain about those too?
and it is very annoying,
Not if you know how to prevent being scammed and use your logic instead of your greed/fear/doubt.
and a lot of my friends lost their funds in eth and tokens that stored their tokens on The mew wallet.
MEW needs a lot of precautions to operate. But there are method to secure it, like using the Metamask plugin and storing them in a hardware wallet. Why dont you people use them and be safe?
