While cryptocurrency prices are extremely volatile leading to greater risk and high profits, one aspect which government agencies in most countries do not acknowledge, is that cryptocurrency is more suitable for micropayment, for a small amount of a few cents or lower
So increasingly websites who get their revenues from advertising are preferring to make payment to users or members using cryptocurrency. Like television, radio, newspaper, magazine, print media, outdoor advertising, the rates will depend to a large extent on the number of subscribers or people who will view the advertisement.
Newspapers and television channels which have more readers and viewers are able to charge far higher advertising rates
Though google pays mainly for clicks, pay per click (PPC), leading to click fraud, there is definitely some cost in having a large number of people view any advertisement, read the advertisement and understand the product or service which is being marketed.
People who view the ad become aware of the product and Google's PPC advertising model does not compensate the publisher for displaying the advertisement.
Paid to click ads pay the person viewing the ad a small amount for viewing the advertisement for a specific period of time. The advertiser also is willing to pay a small amount for viewing the ad . The amount paid is very small typically $0.0003 or less.
It is not feasible to usually pay the advertising revenue share using conventional payment systems like Paypal. Cryptocurrency where payments can be made in satoshi (approximately $0.0003) , it is possible to make payment, especially if micro-wallets are being used.
So while government agencies are quick to label cryptocurrency as being misused for illegal activities, they should also realize that cryptocurrency is more suitable for making micropayments, especially for websites which wish to share their advertising revenues with internet users.
