wwhy eos falling ?
The ICO is a year long. There are new EOS tokens being issued every day for a year. The increasing supply is effectively inflation pushing the price down. You could wait to buy later since the price will likely continue to fall. There is a cap on the supply of 1 billion tokens and 1/3 have already been issued. Once most of the supply has been issued, that may put a floor under the market.
It's true that what you're describing (in a vacuum) will produce a downward pressure on the market price of EOS over time. However, I'm assuming that beberano is asking about the recent price swing of EOS (aka, -30% downtrend in the past 48 hrs). Seems like that's less about the supply inflation and more about the PRC announcement banning ICOs.
beberano - here's some reading to catch you up:
