In my opinion, marketing in such social networks as twitter and facebook performs well. Also for myself I took note of reddit. There sits a very large number of people in the field of cryptocurrency.
Facebook and Twitter is a social platform that has very many users so it is very effective in advertising a product or service because now almost everyone can access it.
and that is a very appropriate way to use for the spread of cryptocurrency.
The fact is that users of cryptocurrency use social networks, but only in limited quantities. Based on this, I think that YouTube and communication on specialized forms can be more effective for advertising cryptocurrency.
I think that everything depends primarily on where a large number of cryptocurrency users are concentrated and where there is an opportunity to advertise new projects. In general, the entire cryptocurrency market, then for this business all methods can be considered acceptable. Although the cost of the Bounty company speaks eloquently about the importance of one direction or another.
