I'm a $GRIN fan and bagholder, I don't care about the privacy that they are facing right now but I'm unloading my big since yesterday, I'm more on chart analysis rather than the development. I'm not selling because of what you said. The chart of $GRIN is really bearish right now due to the effect of Bitcoin price. I still have high hope on MW protocol and probably will enter again once this bearish season was over. Can't afford to lose way higher if I stay on alt coins.
Looks like you sold your bag just few days before -20% drop. Good catch!
