This is indeed a good tactic to promote the project on a channel which is web based and with purpose to create awareness in masses about Bitcoin and cryptocurrencies projects like Hydromining. Italian are also facing economical issues and seeking alternatives ways to store their wealth for the peace of their mind.
I do not think there is any hidden tactics, because I can assure you that this webTv channel is by no means connected with HydroMining team.
Who runs this webTV is always looking for novelty in the world of crypto currencies and when they finds a project that looks good, they talk about it. Nothing hidden and no subliminal advertising. Only information, free and true.
And... yes, here in Italy there is yet a deep economical crisis and a great lack of work, so the crypto world seems for many people a way out of these issues.
As I stated above, these days, there are around many fake and ponzi, pump and dump, ICOs.... so the people is very suspicious and defensive. Because their money is at stake, it's normal that someone sees conspiracies everywhere...
I think is not the case of the italian web TV, and that there is no direct link between this TV and HydroMining team.
