I am worried about the situation with our coin. There are several point:
1) situation with independent stock exchanges:  CREX24 - amazing story with NXB - but other V7 coins work; delisting from stock.exchange => no free market except internal exchange
2) unclear situation to small holders and miners - algo change and possible POS high requirements for masternode (10-30 mln) coins => miner just sell coin and drop price to the ground

PS: anyway devs of NXB try to do real staff (not just sell their premine as other coins do) but progress is average. My recommendation is TO HOLD NXB (no sense to sell at current price or mine due to unclear future)
