Honestly, NEM is a large cap crypto, consistently in the top 20 for years now and not exactly sleeping. I think it's better to be realistic, nem is wide awake and consistently adding value to the ecosystem incrementally, like Apple or Google or Facebook,  anyone who expects multibillion dollar entities to 'wake up' and suddenly x10 their market cap is smoking better hooch than me.

The sleeper coins are way less valuable than nem,  don't try and assume under dog status, nem is one of the big boys of crypto already, a crypto blue chip investment.

You want a real sleeping giant, go read up on CBX aka Bullion, or better still Komodo
