I received an email from MyEtherWallet to claim some tokens of an airdrop I joined. Hovering my mouse over the link, I discovered it's a link to another cgi scripted site.
Interestingly you don't create MEW wallets using email addresses.
Guys be careful and be vigilant.
Yeah, it is necessary to be very careful concerning criptocurrency - there are a lot of fishing sites or other kind of fishing at present. Always check correct URL and do not open suspicious emails
