yesterday I bought GRIM in coinsmarkets at 750 sat .. and now it costs 350sat .. but i still hesitate to buy more coins .. i'm afraid the price will go down ..
To help out a little, coins markets have an extra zero. You actually got those coins for 75 sats which is an awesome deal. It's a new coin so potential for price to totally plummet is less since it will be really cheap to grab them. Hold stake wait for development would be a way to look at it.
