A lot of money won't hurt, but a minimum has to be raised (now, to fight the giants like Google, how much money do you really need to raise, billions?!?)
My main concern is, what is stopping Google to do the same thing (in a sense)? Google rewarding the end user for every search! And Google would just charge a small fee when the advertiser pays the end user!
Also, a lot of advertising is done in closed platforms like Facebook, Amazon (amazon pay per click), Instagram, etc. How is the coin (Bitclave) is going to get to these people?
If you tell me Bitclave will pay the end user, then my reply is, so can Facebook, Amazon, etc. pay the end user and take a smaller fee!!
Just because an idea is great, doesn't mean that it will be easily implemented! (a great example is a few coins out already (in the exchange market) but when asked when their product will release they say it is still in alpha!!
