My bankers told me, I need to help them to create an bitcoin wallet and hand it to them, and theyre too busy to learn it and its very difficult to use, they dont believe cash would die, they deal with thousands of clients everyday who need bankers to create banking account for them, and they know a lot of people, despite having a smart phone, are not good enough to use the phone for simple online banking, they are only good enough to make phone calls with a smart phone, they dont even know how to send texts to friends, they dont believe their clients are capable to create their own bitcoin wallet and use it as cash, their clients would always come to them for help with their banking problem, and bitcoin didnt provide any help as friendly as banker, its why it would fail to gain their attention. And more shockingly, theyre talking about their clients as young as 20-30s, theyre not gonna learn to use bitcoin, only a handful of very young people are tech savvy enough to use smartphone to their fullest, the rest of them are just like our grandma dealing with smartphone.
Yeah - You just wait until this new generation of snowflakes come to age. Their Smartphone skills will revolutionize how internet and phones work together.
I mean seriously - these kids these days operate a dozen social media accounts, 100 aps, while texting 3 group chats and face-timing grandma all at the same time...

I assure you - This new "Shit" generation is exactly what Bitcoin needs to jump into mainstream use.
It's not grandma we want - It's these damn kids to grow up, get jobs, and invest into new tech.
