The main problem of cryptocurrency projects is possible hacker attacks, says entrepreneur John McAfee.
Sooner or later, hackers will focus on digital currencies, he said during the Blockchain: Money forum in London.
The businessman stated that common usage of smartphones and pegging crypto-wallets to them is a great danger.
“Give me your phone number, and in five minutes I will transfer all the Bitcoins from your smartphone wallet to my own account”, he said.
According to McAfee another threat to the security is mining – the most unsecure process in the world.
