Big banks have been failing us for years. At this point Bitcoin is beyond gold in value. I think some people are just afraid of change. We live in an ever evolving world. Coins are faster and more efficient to exchange than fiat currency.
All this talk about a bubble and I don't even believe the bubble has started yet. I have noticed a lot of talk about coins in the news and online forums nowadays. Its gaining interest and I believe the market cap is going to explode in 2018.
