Because as we know that currently not many people know about btc or altcoin.
The price should rise for sure, since the more people who are interested the more media attention Bitcoin will get, the more investors Bitcoin will have, and since everyone wants Bitcoin, and the demand is going up, while the demand is relatively the same, then Bitcoin will rise. I would probably expect a bunch of new alt coins being made and also government regulations and taxes being put in for crypto currencies. Generally, more people knowing about Bitcoin should be a good thing, but that will never happen since it is unlikely for crypto currencies to go mainstream.
