Haven't heard of this token. If the price keeps on declining, then it's better to sell and cut your loss short. Read about the project more. See if the community is active and the developers are still working on it or not. If not, then it was probably a shitcoin and will be dead soon. IF you think the coin still has some good potential and is being actively develop, then why not invest more during this dip and maximize your profit. Though I would prefer investing in those top crypto currencies during this dip. Safer than investing in some random coins.
