Exchange of taxi to Bitcoin, shall it's possible because some people are aged and also tired of man power business, considering the factor that cryptocurrency is only needs brain work not with man power that consumed energy, it's some show encouraging to use what you have to get what you want, obvious as stated by op, Nicole exchanges taxi to Bitcoin.
This is interesting and the same time surprise, if the taxi is the only source of living, I don't think its encouraging from my perspective to operates in such functions now assuming after purchasing Bitcoin and she misplaced her phone and someone happened to have access to in wallet and hijacked all the Bitcoin what will the remedy, irrespective that having Bitcoin is good but to a certain point we have to be truthful to ourselves, people going into Bitcoin does not mean Bitcoin is the only source of generating incomes. In conclusion its good if she have any alternative of getting daily bread than expecting fast profit immediately enrolled to crypto life.
The over aged criteria is another factor that would certainly lead to someone selling her property for bitcoin, normally, before she had taken the decision to sell off her asset (car), she might have saved a lot of money somewhere, who knows. After all, I don't think she will just finalize buying bitcoin without doing a proper research about how to secure her money, if for instance her phone is misplaced, her instructor may have told her how to to keep her private keys in an offline, that's written down on a paper., So there's no way Sher can loose her Moe if actually her phone got lost except she's a novice and didn't look for instructions on how to keep pk.
