People who see the price rise and don't want to miss out I think. Most of that is just speculation, I speculate. Now will it be sustainable and the price will keep increasing at a slower pace and make bitcoin a "solid" currency that people will want to use for other purposes than speculation or will it crash and burn like it already did in the past... Investing in bitcoin right now is nothing more than gambling. You may win big but you may also lose everything. I don't like to play with money so I chose to remain a curious bystander.
