I think that lowering the price of altcoin leads to a disadvantage. After entering the market, the task of any coin is to consolidate the charter. This functionality, universality, as well as investor interest and demand. If the coin does not work. She can not last long.
I think if the altcoin doesn't get many investors it will not be a success and in the end become failed, so it will not earn and will cost the price of the altcoin to go down..
