My grandma is 93 years old, and she was asking me about Bitcorn the other day. That was a bit surprising.
Tell her to buy and hodl!
At her age ...tell her to get a reverse mortgage, splurge it all on BTC, and hope it pumps 100% in the next 6 months and cash out and spend it all...!!!
(serve you right...sending her down this evil crypto path of riches)
