Look at the indicators and support. RDD is now drifting on its support at ~21 satoshi. It is similar to the previous time before huge pumpback in december 2017. RSI on weekly chart is perfect. MACD is going to have positive cross soon. Is this sthe time?
Stoploss: if rdd breaks supports of 19/20 satoshi, then it can go to 8 satoshis before the pump as well so watch out.
Other way: longest target is probably around 340 satoshis (around 1700% of profit)
