Why minimum payout in PTC sites is usually raised after first payment?

Hi It's really unknown thing for me too.. As I have seen few good sites which are having fixed payout and it is low too. So I don't know why they are rising.. New sites are always risky.. they gone in no time. So low first payout is to attract.. and they raise it after it so that they can get more time and meanwhile they can close it... Not talking about all sites.

I think it is for those who figured that they will not get paid after they join and are easily discouraged and for those who want money right away. And to give them an incentive to see if they can go past the first minimum. For me, I could not download from Paypal to my bank unless I got at least a total of twenty dollars (Canadian rule). So the first minimum payment was no good for me.

Hello there, Well, I am not so sure about it since I am still a newbie in this making money online program. I am now using clixsense and ayuwage, but the payment is really low that I won't be able to ask for a payout this couple of months. Have you guys tried those websites out before, what do you think about them?
