I don't hear much people talk about the 350 MA on the 4H chart, but I find it to be quite significant and respected one.
The fact that a 4hr candle closed above it makes me extra bullish even though I have been bullish for quite sometime.
Based on my previous analysis on the 140 DMA (look at related links) I already bought a big stack at the 9900 dip a month ago, but I am buying more here.
You can see on the chart the kind of results it brings when bitcoin breaks to the upside the 350 MA.
