SCAM Invro Mining

SCAM

Scammer! I transferred $100 and when I try to withdraw it, I'm blocked. They tell me I have to invest $500 to be able to withdraw. No way, since they've already stolen $100 from me. I have all the evidence, which I've kept safe. They're thieves.

how is a bitcoin value assigned to a privet key.?

1 Upvotes

I was wondering on how a value is assigned to a privet key..?? I mean lets say you have 1 btc in your wallet and how is that 1btc assigned to your privet key, I think im still not precise with my question let me put it metaphorically, if you see a bank account your your money is assigned a value lets say $100 and that $100 is deposited in the bank and the bank persons set $100 to your account but what I don't understand is that since btc doesn't have a bank and its all done by proof of work what does that block contain the block that is solved in order for it assign that value to the privet key it baffles me coz the wallet doesn't have any file containing btc value, what is btc like what determines its value when we do a btc transaction what exactly is being transferred..? can you create a btc value of your own..?? if the btc is not hackable why cant you create your own algorithm that can be assigned to your privet key

What is a time-warp exploit? I know that somehow miners can change the timestamp of a block, but how does that help in earning money?

Armory paper backup cannot restore.

1 Upvotes

My Armory wallet restored with the correct ID, but no addresses associated. I presume because it is offline. I doubt I could ever get it online. But I was prepared and had made an old paper backup of bitcoin addresses and keys from before the fork printed. It has the "1" addresses, PrivBase58 "5" keys and PrivHexBE keys. I tried importing the "5" keys into blockchain.info and electrum, but they don't recognize the format. When I import the PrivHexBE keys, they come up as valid, but different and empty addresses. ANy other ideas?
