For most people bitcoin seems to be dangerous. It's online money and people don't fully understand or trust online.
Think about the hacks/ criminals that happen. Most people are just scared.
Hacking is very essential for the cyber world, and that's one really a very inevitable and bitcoin is really a has a great value now. But the security of
online wallets are strong, I don't know if there is already a news that an online wallet network has been hacked.
But online things are hard to be understand for those people who really don't know what it is and they just only know the word hack.
