Many hasn't gotten that time to read the Bitcoin whitepaper before making such judgement about Bitcoin going down. In as much as some who doesn't see Bitcoin going far doesn't mean it will fall instead it will bring something that would rather change their negative mindset or convince them totally that Bitcoin is here to stay for good.

They don't need to read all the Bitcoin White Paper or understand all technical things in Bitcoin protocol. It's for programmers who can understand code but as investors, people must read to learn basics of Bitcoin.
Learning basics will help them to see potential of Bitcoin blockchain for privacy, anonymity and decentralized network, censorship resistant.
They will understand about Bitcoin total supply and its scheduled future supply until 2140.
Those basic knowledge is enough for them to build up their belief in Bitcoin and start to become a diamond hand Bitcoin investor.
Controlled supplyHow is the 21M Bitcoin cap defined and enforced.
