Like all other things, it has its pros and cons. I'll say one con is that it will be limited only to those who have access to electronics.

Bitcoin itself is a currency, not an activity. Even if what they meant is the campaigns, I would agree with you. We use our brains, not our chances.

What does "uninteresting" actually mean? Is it just about the relevance of the post to the topic or about the novelty of the post?

   I think the existence of bitcoin, and other cryptocurrencies, reveals the true nature of money which we had long forgotten or never really had the right idea about. Money, as defined by the Webster's 9th New Collegiate Dictionary, is something generally accepted as a meduim of exchage, a measure of value, or a means of payment. Practically, though, that "something" is a concrete object, not just a mere idea. Thus, money is subject to depreciation - as seen in the decline of value via inflation and similar situations. In this sense, the standard value of money doesn't seem so standard at all and it won't be much of a "generally accepted" medium of exchage. This is where bitcoin is more of a real money than the physical money itself.  We don't control it's value, unless everyone - really, EVERYONE, at least those who use it - agrees so.
