They are saying Ethereum is going to surpass Bitcoin. Ethereum was made by a Canadian-Russian. I wonder if there's a significant risk in the creation of many other digital currencies, which could saturate the market for them. Also, although payments can be made with Bitcoin, it's not well-adopted enough for it to be considered a currency. Right now it's an asset like gold.
Another interesting thing is that company's have started to accept coins to raise capital. They're called Initial Coin Offerings as opposed to IPO's and are apparently gaining popularity in tech.
