It's not just Bitcoin, Altcoins are going crazy as well. Just invest in any altcoin and it will be up or down 20% within 24 hours. It's a highly volatile market, do you call it a good investment, seems like a gambling to me. This market is so crazy. I just feel bad for the people holding the last bags of the coins, they will probably lose all of their money. Initial investors are very happy as they made so much money and cashed out. I bet you this market will crash very soon, I don't know exactly when but it will be a big crash.

Every coin should be backed by a revenue generating business, then it's a smart investment, but right now these are all speculations. Money is being generated from money, everything is digital, there is no physical activity or tangible asset, apart from waste of lots energy. I like steem coin though, at least there is some business value to it. All the people who are so confident about this revolutionary breakthrough blockchain technology, I'll see their reaction when Government will intervene, they will be the first ones to chicken out. Do you really think Government and all of these big banks will let you have it your way. If Government bans it or regulate it, it will lose all the attraction/perks and everything will go back to normal.
