Great video mate, although the title is a bit clickbait. So much questions in crypto. I will give you my opinion and answers:

1. Crypto is getting traction in another group of people and investors this time. Bitcoin is still surviving and will prove more and more that it's a safe and practical investment. People are HODLING and that will raise the price of course.
2. With every wave of new people joining crypto, the main goal for them is to make money. Now the price is mooning everyone wants a piece of the pie. Entrepreneurs read about all the millions raised with ICO's and they try one of them own.
3. I don't follow BitConnect. Can't answer that.
4. People who invest a lot in a product will preach their choice. It's the same with Andriod vs iPhone. When you buy a product and use it, you paid a lot for it, so you protect your choice. And on the other hand, people are afraid about FUD for a crypto they invested in, they have a lot at stake and get more emotional.
5. Regulation is a prove the blockchain/crypto will be taken serious. There will be less freedom, but I think it will boom big time. Business, banks and financial companies will dive in crypto. They will bring in big bucks!
6. Prices will rise, because in a financial crisis other financial products, like gold will rise. The next big crisis will probably be a transition to a new monetary system. It can get really big!
7. Everyone loves stories about easy money. :D
8. It will be a graveyard with unsafe crypto blockchains. Only a few big ones can be trusted and will be safe. Probably the top 50.

Hope you like my comments. Looking forward for your view on this. :)
