Let me just say that blockchain technology is the most comfortable technology people have ever wanted

Blockchain is actually comfortable when you know how to use it. Due to its technicalities a lot of people have decided to stay away from it. But once you are accustomed with it am sure you will see the comfort that you have spoken about.

regulation:

Yes , regulation in the blockchain becomes an issue when there has been a fraudulent activity of any sort.

We must all admit that even in the centralised sector there are way more acts of fraud than in the blockchain. And the blockchain even makes it hard for fraudulent acts to happen.

Hackers can access any person information and use it against that person. We know that anything that is online can be hacked.

Yes anything that is online can be hacked but it is very difficult to do this.
