TLDR: SHORT now (880~1000 satoshis) until Line1. Buy above Line1 (just in case of great volume, then we can expect a bounce there). If Line1 breaks downwards, sell it and wait for Line2 be touched. Buy above Line2.
This analysis is just based on the chart. I don't know anything about RVN fundamentals.
As you can see, in just one week RVN had +400% gains. Obviously, most people will be selling here. If you missed the train and you really believe on RVN project, do not FOMO. Wait for retracement, then enter a long position. Every parabolic move has an end, and RVN already started its retracement. If you are in profit, just short all the way up from now (870~930 satoshis) to the next retracement levels.
As you can see on the chart, we have Line1 that will surely be touched on the next days. Maybe we can get a bounce there. This case is represented by the yellow arrows path. We must see this movement if we have a very very big volume on RVN/BTC next days. You can try to LONG next to the Line1, and put a stop-loss under the Line1, in case the market just rejects it.
If you see the Line1 being broken, wait for re-test. We're likely to see the green arrows path, re-testing the Line1, being rejected, and then going to the Line2. The good trader will be willing to buy right above the Line2, expecting the upwards movement that started on 15 october to continue. Remember, the good trader is not buying now at 900 satoshis.
