I bought yesterday for 4.40 each and today price is 3.50... I'm always that lucky

Be patient and continue to wait because DIA is still a good investment option during this time. I guess this coin will soon surpass $8 by the end of the year because looking at what's happening this is one of the most successful Defi projects. I bought from the price of 2.8$ and still have no intention of selling because I want to sell the DIA at a higher price.
