The problem with this technology is the so called "Comfort Factor".  Everyone wants to have a system that is user friendly and very easy to use.  
Consider what this technology is based off of, the very basic construct of a public key (your address) and a private key.

Knowing these two points, you would have to come to a conclusion that the most important factor in all of this is the private key.  If you have created your private key on a hot machine, your setting yourself up to fail and it is your own "Comfort Factor" that is the downfall.  

If you want to get the message out, the message should be loud and clear.  Do not ever create a private key on a machine that has ever or is connected to the internet.  I could take it one step further, you should never create a private key on a machine that has been on the internet or connected to the internet and also has USB activated.  If you do a little research you will see the dangers behind active USB ports.  There is a frequency hole!!  

Your currency will always be safe on the Blockchain if you and only you are proactive with your private key and create this key in a fashion where no other person in the technology field has a chance to achieve access to this key through your network.

Anytime you create an online wallet and make a key, it is like going outside and placing money on the street and putting a rock on top of it and thinking "Tomorrow it will be there".  Wallets on cell phones with private key entry, I can only shake my head even thinking about it.  

Take your money serious and stop thinking "Comfort Factor".  The security in this technology field is not easy and will never be easy.
