Sincerely speaking those beneficiaries of this electric power supply would be curious to know more about this Bitcoin mining and it's network, and before you'll know it more persons would want to adopt Bitcoin. That is why is why giveaways and promo are one of the best strategy of advertising. The miner might not be advertising Bitcoin, but his deed has already done the advertisement unknown to him.
Advertising bitcoin through this process is a win-win for both sides. Advertisement is going on and the people are benefiting from the electricity being generated from the mining tool. Learning bitcoin through the process of mining will be very hard for beginners who are just hearing about bitcoin. Without being a computer guru, I don’t think you’ll have anything to understand from the mining aspect. This will let the people know about bitcoin but will still need someone to help them understand the basics of bitcoin before going as far as mining. Since it is even located in a rural area, it means the people there most cannot be literate enough to learn from that place easily. The benefit of the electricity they get is what is more important to them regarding the mining tool in their town.
All I'm trying to say is, the market cap of Bitcoin has been increasing by there are no advertising team out there who are being paid for advertising Bitcoin to the public.
Bitcoin has gotten to a point where no more advertising is needed and people will just be adopting it. Gone are those days they few people know about it and the very few news that always come out about it are mostly negative ones and that didn’t make a lot of people to pay more attention to it. Bitcoin on how it has performed over the years have paved way for himself to be known. Today, both positive and negative news are all in its favour as people get to know about it and become more inquisitive about it through this process.
