Well for an investment banking company it is not too late for them to enter into the scene as they will most likely be part of the side which controls the price movement of Bitcoin, but I don't know why he thinks that Bitcoin will ever have a price movement that is below 20%? I mean he knows that Bitcoin is a decentralized currency the only way it gets stable is if no one is willing to trade it anymore. For me the price movement of Bitcoin makes it more suitable to "trading" as although making it more risky it is also profitable.
True. As for the price movement, we have seen it move below 20% but people still trusted on it and bitcoin already shows that in can recovered from such crash in the past. So it means that even though it plummeted, people are still buying and entering the market with their own "risk". And that is the beauty of trading bitcoin, traders likes us take advantage of its volatility to make profits. After all, everyone doing trading is looking to make profits, not only in bitcoin market, but other markets as well.
Wall street is already opening a futures options trading on bitcoin so this sounds probable..
Yes, NASDAQ as well have plans to launch its own bitcoin future contracts in Q2 2018. Let's see how it goes. And this trend will continue for the couple of years. Speculative asset or bubble, bitcoin will really be the next big thing, financial institutions will be involved promoting bitcoin whether they like it or not.
