If your bank account is hacked and your money is stolen; will you say banking is fraud, don't put money in banks?
Definitely not! There is no way that we can put a blame on banking system for such kind of activities.
I dont really think so that the ones who actually know about bitcoin will be having any kind of problem or issues to go for investing their money into bitcoin.
In fact, investing in bitcoin is really a good opportunity for them as they are actually making out huge profit by investing their money into bitcoin.
But there are really close minded person which once they do experience such hardship or failure because they got hacked they put all the blame on the thing which involves on it which is really not a good thing to think off. We should always remember that we are always responsible on all of our actions and knowing that hackers and thieves are everywhere this is why we should really be aware on what we would plan to do.
