They're optimistic because they recognize most traditional currencies that are bound by government are due to fail because of irresponsible spending and corruption. There is no brains to profit from BTC. you buy in, wait until larger currencies begin to destabilize, and boom - your BTC is worth more than it was tomorrow. For some, it's not optimism, it's just accepting the harsh reality that paper currency is worth something because the government tells us it is. And we should trust the government why?
Indeed. I think most of our old men are stuck on that kind of view. Traditional view.
Even if they don't trust the government, it's just the simplest way to invest with no trouble which is wrong.
Investments should always have their risk. Bitcoin has risk, no doubt.
But, it had been years and it's still getting more valuable so I guess that answers how much risk were lowered because of the trust that is obtained from its followers. Here's the good part, it's growing.
