For my experience with them it is not a scam, but their system is somehow strange. About solo mining, yes they do not accept more than 1 mhs and there is 20% fee if you withdraw dogecoins. From solo mining with 1.2 mhs I earn around 1eur per 24 hours which is 1.12 usd = 6600 dogecoins per day. 6600 dogecoins per day, how does it sounds? How much is 6600 - 20% fee = 5280 dogecoins. Everyday I withdraw between 5-6k dogecoins per day with 1 mhs. I was mining doge in many pools, but with 35 mhs I could earn max 2500 coins per day.
Why to run 35 mhs for 2500 coins when I can run 1 mhs for 5k dogecoins even with 20% fee. Which option is more profitable?
I've purchased demo contract when I started and everything was fine, min 1.70 eur per day with it. Now I am on starter contract and soon will report.
I don't know why some peoples cry about paypal and cryptopay. I don't know another mining pool that lets you withdraw by paypal, do you?
Please, be objective before you say it is scam. Because of peoples that were saying it is scam I started mining there too late. I was mining on a loss with 35 mhs at anomining pool... If you have 2 ips become referal to yourself and put 1 mhs, and you will earn more.
