It depends on the environment and society support. If you live with society which make a deal to not use money, it's possible. You can live like in 10th - 15th century where everything can be bartered to get something. No money, but they live. Gardening, farming. Banana traded with chicken eggs.

In many country, government already know that bitcoin exist there, but nothing happen. Some of them just warn and so far just warning. Some other banning but not in real act, just speech and said "we are banning all cryptocurrency" no more real action like blocking all website related to cryptocurrencies. Just something like drama.

Why you didn't straight ask your question on that thread man? Well yes I appreciate your willing to lookup the answer on this terminology thread. But it also not bad to ask there on the tread you've mentioned above.

I think explanations will far not enough to make someone understand it. For me, I'll will just explain that it is a cryptocurrency based on blockchain technology which born to make financial field better because of its system like decentralized, timestamps and many more those pointing in transparent financial system, like there will no double transaction, manipulation and something like that.

Then it become famous because its price and inspire many other coins established. I just will explain like that and will refer he/she to googling it for more detail

Because I think explanation will not never enough to make someone really understand.
