Hey, thanks for kicking in. You got some good points! Here is not really the same case. Obviously the blockchain = huge low cost database technology will be used and will survive. Buying currencies (they are not shares most of the time) are like kindof betting that someone in the long run will use this product with this currency, so it will be a huge demand for it, if not you loose. Now all the market trend is down for a few days, and maybe will be for a few weeks more, who knows. This doesn't matter in the long run, who buys stuffs should more or less invest in the technology with a big risk / reward ratio, and shouldn't be freaking out when prices drop like 50% :) (after a month of huge gains, it should go down at some point)
