Bitcoin is vulnerable and perishable.One can lose it during transaction,wallet hack or theft and it is not recoverable.I think that is also one of the main reasons stopping people from using bitcoin.When it comes to money,safety takes the priority
You can also lose fiat if you drop it, no way of refunding it back. Having to lose your wallet from theft should not be a major turn off. You can take security precautions against such attack. Frankly speaking, it would be hard to get virus on your computer if you do not download programs randomly. (Excluding physical access).
i think it is because some are afraid of the new things to learn. You will need to understand it. More to learn. Some just want to live on what they have. And dont want anymore to learn what is this and what is that.
This is one of the reasons. For the time being, you need a bitcoin wallet and that need computer access. This is not suitable for most over 50s.
Says who? Most over 50s have a working computer and little to no skills is required to use Bitcoin. In fact, I have seen people in their 60s-70s using smartphones.
