because they fear many negative effects with bitcoin, so they will be afraid of losing their money, so they will be afraid to invest in bitcoin. but I think investing in bitcoin if you really can get bitcoin in a good way, for me you will also get more profits in the future. because the price of bitcoin every day is also increasing.
The main problem lies precisely in distrust. People are used to investing their money in gold, for example, because they know and see what it is. They can touch it. And Bitcoin is something new, modern, therefore it can not be touched. Therefore, there is distrust. I think that if they see by personal example how to earn money using Bitcoin, they will begin to trust it.
