We've heard exchange getting hacked and millions of dollar worth crypto being stolen.
Last year, Myetherwallet was exposed and hacker penetrated and stole alot.
Scam ICO made away with millions in recent years.
Crypto traders and investors are taking precautions so as to not fall victim. This doesn't guarantee Scam free Crypto space coz right now someone is being scam.
What could be the biggest Crime in cryptocurrency
I have never heard anything happen to myetherwallet and it was Etherdelta that was hacked. Also, phishing emails were sent to almost all bitcointalk users as the email database was leaked during a hack earlier. Hence, most users were affected but those that did not click on suspicious links had their wallets safe.
Edit: Checked it now and there was a hack in the extension of MEW. Glad I did not access MEW during the hack.
