Plus it's not like you cannot rebounce from a steady decline, look at ETH example, so NXT will be fine:
NXT can easily rebounce from it's decline, just as BTC or ETH did.
Of course Nxt can rebound. One difference between NXT and ETH/BTC however is that NXT has 0 inflation while BTC/ETH have 8-9% inflation. The fact that Nxt's market cap , tx volume, and price compared to BTC has been deteriorating without the costs of PoW and inflation should be troubling. The data right now indicates that early investors are dumping their coins for other assets or coins. Whether or not this trend will ever reverse is dependent upon adoption exceeding the coins being dumped on the exchanges by early bagholders. Since NxT doesn't seem to be focusing on merchant adoption much and appear to be marketing it as a financial platform , than the only hope they have is some "bank" adopting their blockchain and bringing it mainstream, which IMHO is a risky bet as banks tend to be focused on creating and controlling their own products.
