I like paper money. I like to feel the buying power in my hands :p Bitcoin makes me feel like a robot. I am not saying paper money is better tho.
Thats true, and it was said in most of the opinions here that a cashless society will not be a very good way of innovation, which I agree with cause you can see a massive accounts will be compile in one or more companies or entities whixh may be a bait for the hackers to bite , and as they say it may also happened that if you are not a good citizen your profit will be hold or account which is unfair.
For now of course digital currency will still be the pros and cons because I think people are still more comfortable using paper money for many reasons including me. but some generations below us may have different views on financial transactions. no doubt some of us also prefer to pay by credit card because it is more simple. I think that's a sign of a digital currency will develop in the future..
