Are there any minimum of deposits ? Or you crediting every single "satoshi" i send ?
They don't have a minimum on their deposits. You will receive every satoshi or altcoin you send on your deposit address. If you have more questions you can check their support center/faq page.
We do not have a limit for the deposit. You can send any amount.
How long do I have to wait to get a response?
Fastest way to get a response is by opening the chat box on the bottom right. I've used it once and got a reply in 5-10 minutes.
