What does the future hold for cash, and can btc become an alternative?
The history of currency system have been changed several times and now we are used to use cash. So in future gradually it will change and will be invented a new currency system and it's pretty much sure. Now people are showing interest in Digital Virtual Currency. And many people now don't like to carry cash even it's more insecure. So in near future The popularity and usecases of Cash will gradually be decreased. Bitcoin can be a perfect alternative of Cash as it's much secure, Decentralized and easy to make transections and anonymous. But some limitations are the main problem for mass adoption of Bitcoin. But Bitcoin has some limitations like it isn't suitable for kids and old people and it can't be used without internet.
So it will be a perfect alternative of Cash in many terms but cannot fulfill every requirements because of it's limitations.
I can fully understand that it's more difficult for an older person to learn bitcoin (even if it depends on their upbringing, alertness and curiosity. Some people are older at the age of 40. Some others at the age of 90 ...), but for children I really don't see any problem. Children learn quickly and it's common for them, for example, to speak several languages from an early age, especially if they come from mixed couples or were born in polyglot countries.
We shouldn't underestimate children's capacity to learn. When they don't learn at school, it's sometimes because they're bored and the lessons aren't lively. It's up to adults to make learning fun.
As for me, my two children quickly learned to use my bank card.
