It would be possible only with consent which is a good thing. We should allow people to install a plugin or extension to let themselves be tracked in exchange for hourly payments.
It could be marketed as “get paid to surf SAFE Network” and be taken viral by rewarding people with higher hourly pay for every new user they convince to opt in. This would market SAFE Network itself but also bootstrap an economic ecosystem for advertisers.
The people who agree to be tracked would be the eyeballs. These people would also be in pretty high demand because every DAC/DApp/Altcoin developer would have to reach them.
So for example you could pay these people $1 an hour just to be tracked. That’s a trivial amount of Bitcoins but you’d for sure find people for whom that is plenty of money. The amount of money they get paid could also be determined by algorithm depending on how many people are online at the time so that some days you can make $5 an hour and other days the minimum of $1.
Now how would DAC developers get clicks? They would offer free shares in their DAC to the first 100 people to click. Then lower the amount in the 500 who click after that and so on. This would get people to click just to get the free shares.
This would also immediately create a huge market.
