Technically, its not risky to invest because there is not much value left to lose... The current holdings is a little "insurance" for a possibility of sudden growth, anyways, waiting for price declining even more. The price is too low to sell, and there will nothing happen up to september so its not very smart even to buy too much. By natural price hyperbolic declining the price will go below 30 sat in few weeks.
The only problem is that its safer to stay in ETH than in utnp.
