What being new to the site has to do with giving my opinion on something that everyone should look into before sending their money to a company that may end up causing them money at the end. They got their money after posting what was going on. 10 days is a long time. During that time they could have used the money invest it and make some profit out of it.

If the credit card has been reported stolen the transaction wont go through. Chargeback is something that every business must deal with every second. Do you actually think that Apple, Samsung and etc make less money because their customers are doing fraudulent transactions or because most of them are honest.

So let say you invest 10k in miners by sending coins to them and then you find out is all a scam, what government agency are you going to run to, to get you coins back? If you do a wire transfer you have no way of getting the money back even after explaining it to the bank. They have all the hands when it comes to making the transactions and you have none.
