The last ATH wasn't fueled by fundamentals or how well the foundation was managed. It was based on speculation and fomo, plus a bit of pumping from the WeChat rumor. The whole of the crypto market was pumped during that time on the back of the BTC highs and additional liquidity from selling off of free forked BCH. When the whole market has large price rises in the future, NEM will also rise along with the other alts.
Any technical enhancements and Catapult release will be a bonus.
