thanks.

trying to start small with 5MH/s for DASH but always getting the error:

The daily limit for credit/debit card orders is $5,000 (up to $20,000 a month). Your current daily volume is $0 (monthly $0). For larger orders please click on the drop down menu to select a different payment method.

any idea what's this?

Don't use credit card to purchase.
Use bitcoin.
There is no limit to the amount of hashpower you can buy with bitcoin.

Here is the RegalCoin white paper that explains what it is and how it works.

Just send me a PM for my referral link if you are interested to invest.

I am standing by now.... 

You got PM.
