my father and mother from my family have no knowledge of bitcoin so they keep persuading me to invest in bitcoin.
They don't understand bitcoin so they persuade you to buy it? Did I read it right?
Why? This sounds a bit crazy on their part.
My parents thought that bitcoins that cannot be seen or touched cannot be an asset.
So they are against bitcoin, but keep telling you to buy it?
Now I'm confused even more
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.
Safer usually means less profitable. For instance, one of the safest investments is to buy foreign currency of a country with strong economy compared to yours, but this will barely allow you to make any money.
