I't s just confirmation of my thougt, that Bitcoin is too complicated for ordinary person to handle. My mum would get lost if she would had to make transactions alone.
It really is. Even for people I know that deal with programming, computer repair, etc., it has proven to be tough because of the principles involved. Basically it ends up coming down to "just trust the system" (and, really, why should people do that?).
They shouldn't, but we can help them
This community has many computer experts, cryptography experts, and mathematicians all readily available. If someone wants to know why they should trust the system we can explain it exactly, and to what degree there are any risks. The forum is open to public participation so anything said here can be challenged anytime.
... The technical issues will go away over time with easier and easier to use wallets and services, but as for the exchange rate risk.... I don't have a response for that one.
Tell people even established currencies like the dollar do lose value over time. When people diversify into alternative currencies like gold or bitcoin they can have some of their money go up sometimes instead of always down (felt by goods becoming more expensive). That can be a fun idea for people. They don't need to jump in with both feet, but they can play with inconsequential amounts just to see what else is available and get more familiar with how things work.
