1. They do not understand clearly about bitcoin and blockchain
2. They feel so dangerous investment
3. They just only bitcoin and crypto through internet news, it is not enough for investment any thing.
4. The price bitcoin is so high although it can not use in normal life
Yes they are totally doing wrong because bitcoin is really a safe and secure investments and only those are afraid of it who are not aware of the bitcoin features properly but those who know the worth and power will never find it risky, bitcoin is risky for panic sellers and those who are greedy by nature so that they sell it for panic to get quicker and higher profit.
