Especially useful in places like Venezuela! (Coming soon to a country near you!)
yes it is useful, and you do not need to exchange it to somewhere, we can use cash everywhere because it is what they are accepting. you do not need to go and find somewhere for the exchanger for you to use.it is also what is in use in every country, but then there are also disadvantage of having a cash and there are advantage of not cash, like bitcoin.
Well that is the advantage of cash over Bitcoin, its availability, volatility, and utilization of cash. It is available everywhere, specific cash for specific area; its price will not make any discrepancies in just a matter of hour unlike Bitcoin, it has its stable price; and its utilization is quite very obvious.
Then in Bitcoin, I've mention that volatility is also an advantage of it, since just a year ago its like $2k dollars or so but now its $5k, you see that's a lot.
thats not true at all, just look at how the british pound tanked when the results of the first brexit vote were announced. the pound dropped something like 20% (not entirely sure, someone can look it up exactly and correct me if they wish) within 24 hours. availability? i cant use my dollars if i dont have my card or physical money available, the same way i can't use my bitcoin if i don't have access to my wallet and private keys. availability? credit cards dont work without an internet connection, neither does bitcoin. no cash? can't spend, and there are 'paper wallets' that can be created with bitcoin private keys as well. none of the point you present are consistent in the context of the subject, do some more thinking.
