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
Since there are lack of governments control in ICO project then some bad people create ICO project to scam people. I think government should have more role in this investment world but not to restrict or ban cryptocurrency. Government's afraidness about cryptocurrency is too excessive. Now most of hackers are give more attention to bitcoin because they cam get a lot of money from it by stole it or any methode. There are many crime so we have to be careful. I warn any people to always make sure that the website that they visit is right because there are many fake website so if you use service in that fake website then you can lose your money.
