GRS is one of the rare coins that haven't exploded yet on Binance in the previous months (except December pump and dump).
If we look at the chart, we can see a bullish divergence on MACD and a growing RSI. Bollinger bands are showing a movement that will happen soon (weekly timeframe).
300% seems to be a reasonable (yet awesome) target as there is absolutely no huge resistance before 0.382 fib area.
This is not an investment advice, just sharing my thoughts. Good luck everyone!
