Hi guys
If I install the wallet on another pc and use the backup.dat it should work, right?

When I read the name of the topic I thought wow, somebody again trying to bring this back to life, but that try is already a year ago.

The problem with this coin is that the inflation rate is ridiculous.  There have been 14,600,411 coins produced as of now, but the miners are blasting out approximately 15,000 new coins per day.  There is a long way and a lot of massive inflation between now and the max supply of 2,500,000,000 coins.  If there is still a dev anywhere, you should cut the max supply to 21,000,000 and stop it for good when it gets there.  There should be no more mining and no more staking once the supply reaches 21,000,000.  When the supply gets there, people should have to purchase them on the exchange if they want any.  The current price of 250 satoshis is disgustingly overvalued for a coin with billions of supply.  You need to stop it at 21,000,000 so it can be a relatively rare coin before it gets out of control.

You can mine with just field 3 right now, which is 8gb.  As the difficulty increases further fields will be activated.

At the point it gets to the larger fields, I expect that people won't mind buying some multiple TB SSDs to put them on as there will clearly be enough interest and probably enough value.

I ordered 4 requesting PayPal as payment.
I received an invoice/payment request to a Russian individual's name.
My payment options did NOT include PayPal credit 0% for 6 months on purchases over $500.
This to me was a red flag - seems to be a person-to-person request and not an online purchase - meaning no buyer protection.

I am not comfortable enough to move forward with payment.

I don't know that I would trust paypal protection exactly.  I have used it with Ebay in the past, and while the results were in my favor, it was a general pain in the ass.  I do think they tend to err on the side of the customer though.  I had a buddy with a business selling telemarketing data and he had to stop using paypal due to the insane amount of chargebacks that were not found in his favor.  That said, just use a credit card.  If what you buy doesn't arrive or work, Visa and Mastercard are amazing when it comes to fraudulent transactions.

It seems they are "emailing you" the paypal invoice AFTER the fact - this makes me worried as I'm not sure we'd be covered under paypal guarantee seeing that we didnt pay via paypal ON the website, instead, we're paying via email invoice later.
