Nothing is truly safe. Bitcoin has many advantages over a debit card and as time goes on it will become apparent why it is better than debit/credit/banks. Right now it may be hard for people to see that but you simply don't have to participate.
It's not hard to see that. The real early adopters have seen this comming back in 2010/2011. And look now, they are greatly rewarded for their trust in Bitcoin. Only ignorant people find it hard to understand that Bitcoin as technology and currency is far superior compared to the old fashion financial system.
I dunno if it's ignorance, but rather years of indoctrination from the fiat financial system that it's the best and safest option... They just follow like sheep, like they were taught.
Then you have strong supporters of this system and shills being paid to spread fud and confusion about Bitcoin, so it makes it even more difficult to understand.
Let's take all this in consideration before we judge them...
