PTC : Why are they changing from paypal to alertpay payment ?

I get paid through paypal at a few sites such as Fusion Cash and some survey sites. I was doing some work at Microworkers and the first time I got paid it was through paypal. There was a small fee, but that was okay. They also offered alertpay and moneybookers, two sites I'm not familiar with. I had built up at Microworkers to over twenty dollars and was checking to see how much I could cash out after the paypal fee and was shocked to find they no longer did paypal. At first, they stated on their site they were having some problems but paypal should be back soon. Seven month later it's obvious "soon" is over. Apparently the people who "hire" can use a credit card to pay into the money they pay the workers. This option for getting paid is not available. So I opened an alertpay account but the fees are so high. I think I will build up my earnings again to over fifty dollars, cash out fifty, and quit the site. Amazon Turk at least will put the money in your bank account or on an amazon gift card. Much better - plus no fees.
