I love DENT, this is a very long hold project for me.  It really all comes down to the existing telecom companies playing ball with Dent as to whether this will be a unicorn project or not, even without these companies DENT can still have a massive effect on the market.  Am considering buying more this week as it's really undervalued right now, in 5 years you can judge DENT's successful or failure, but right now they're doing quite well and progressing this project at a rapid speed!
