The price becoming lower and lower, I've experienced this in several project before, this happens mostly on the first day of the token listing, if the exchange the token is listed on doesnt have large liquidity to absurb the multitude of sellers trying to sell for whatever amount of profit they've managed to make, so I think it's a normal thing, it's absolutely nothing to worry about and it's even a good opportunity for you to grab some few cheap coins if the project is a highly promising one, with time, as the coin gets listed on better exchanges with higher liquidity, the price will stabilize.
