My parents thought that bitcoins that cannot be seen or touched cannot be an asset. They think that investing in physical assets such as gold, bank deposits, land etc. is more profitable than Bitcoin. But even after I convinced them, they are not ready to invest in Bitcoin. They don't want to believe in virtual currency.
They have to realized that sometimes, things that are not seen tend to last more than things that we clearly see or feel, they are older people, senior citizens and have been more experienced in many ways than we do but that doesn't mean they are updated as we are in this present generation, during their time, things weren't like this, but now, they may feel it's a means of scam to exercise fraudulent acts since they have heard about many online related scams trending, they may not want to hear or give any digital network attention for them to try, but as for anyone who knows about bitcoin and gold, you could tell well that bitcoin is currently having higher edge than gold.
