i think, usb miner is not profitable right now, I don't know how much hashrate is generated for USB miner. but by comparing hardware miners like antminers that cost much more. so, it will waste your time and your own finances
A Gekkoscience 2pac will give you about 10Gh/s out of the box and can be overclocked to about 25Gh/s. So not alot in the grand scheme of things..... 25 GH/s gives you a 1 in 320 million chance of finding the next block. Note that the odds of winning the Powerball lottery jackpot are slightly better (1 in 292 million). The odds of finding at least one of the 144 blocks mined in a day is 1 in 2 million. The odds of finding at least one block after mining for a year is 1 in 6000.

Oh, let's say you had purchased $4800 in Bitcoin at the beginning of this year and held it rather than putting it into this MLM scheme as you did. You would have purchased around 5 Bitcoin which would be worth US$28,000+ today - 9 months later. TL;DR What did you make again? So where does the money come from?!? Again, people who don't understand bitcoin and bitcoin mining make this mistake time and time again. Yes, I could have purchased 5 bitcoin at the start of the year. And that's what I did. And I paid BCN another $5,000 (in the form of 5 bitcoin) to get started in mining. A total of 10 BTC. There is a big difference between the two. Bitcoin is both a product and a service. The former serves as a store of value, the latter as a payment method. After their own analysis, people who want to invest in a bitcoin mining programme will buy into a mining programme for whatever reasons, for whatever returns, for whatever time frame, for whatever risks, whether it is paid in cash (USD) or cryptocurrency (BTC). BCN allows people at an individual level to find bitcoin mining viable. Otherwise, it will be left only to the big players who have millions of dollars to invest in tens of thousands of mining rigs at a go. Individual miners will eventually be phased out as the mining difficulty increases, and your chances of profiting from this industry will only be limited to being part of a large mining pool. If everyone thought the way you did and preferred to just buy bitcoin and hold, no one at an individual level would be doing bitcoin mining. Without the growth of the bitcoin network by people investing into mining hardware and contributing it to the network, it wouldn't cost as much as US$30 billion to hack the bitcoin network today and far easier to achieve more than 50% of the computational power of the network for a successful hack. As it is today, any hacker with that sort of resources would be better off doing mining himself than trying to hack the network. The bitcoin network looks after itself, so to speak.
It isn't that hard to figure out. If you invested 5 BTC into BCN mining and you ended up with less than 5 BTC, then you have lost money. You seem to feel that your support of the bitcoin network justifies that loss and I have no problem with that; however, there is a problem when the money losing aspect of BCN mining is hidden from people.

The seed is all the information that the wallet needs. All addresses are generated from the seed. BIP-32 describes how addresses are generated from a seed. You can generate a private key by hashing the seed itself. You can generate another private key by hashing the first private key. You can generate as many private keys as you want by hashing the previous private key. If you start with the same seed, you will always get the same private keys, so the seed is all you ever need. BIP-32 uses that concept.

You need a BTG wallet to send your BTG to. I don't think they exist yet.

I had some bitcoin in coinbase that I transferred to my Trezor AFTER the bitcoin GOLD hard fork... am I in danger of a replay attack?
First, a replay attack is not really an "attack". It is simply describes when a transaction intended for one chain occurs on both (because nothing was done to prevent that from happening). If you sent BTC from Coinbase after the fork, then you may or may not have also received BTG. It depends on whether the Coinbase address has BTG and whether they prevented replay or not. If Coinbase does not prevent replay, then it is possible to suck BTG out of Coinbase. Simply send BTC to Coinbase using replay protection, and then withdraw the BTC back to your wallet. Assuming that Coinbase does not prevent replay, any time BTC is sent to you from an address that also has BTG, you will get the BTG, too.

When you loses wallet, it has the effect of removing money out of circulation. Lost bitcoins still remain in the block chain just like any other bitcoins. However, lost bitcoins remain dormant forever because there is no way for anybody to find the private key(s) that would allow them to be spent again. Because of the law of supply and demand, when fewer bitcoins are available, the ones that are left will be in higher demand and increase in value to compensate.
if I will lose my bitcoin, then the bitcoin exchange rate will continue to increase. You are assuming that the demand does not decrease (like it did in 2014-2015).

what will happen if all signature campaigns end,? whereas most of us look for bitcoin through campaigns. is it possible that this forum will be left behind, ..? I also may be confused when this happens Well the traffic and activity of this forum will be decreased significantly if that happens. Lets hope it does not. No doubt that traffic will drop considerably ... I like the signatures campaigns , I found it very original, I had never seen it in other forums. I would love for traffic to drop because the quality traffic will remain, making it a much better site. I already have most of the sig campaign posters in my ignore list, so I don't think that I will miss anything.

As a beginner I am a little confused with this forum, what should a novice do for the first time in this forum? and what should I do to avoid mistakes in taking steps to get bitcoin? I say thank you in advance. You are confused because you (like many others) believe that the purpose of this site is to make money. It is not. The purpose of this site is to learn and discuss. I encourage you forget about making money here. Read everything and learn to search for answers to your questions, and you will make much more than just money.

One possibility is that advances in cryptanalysis or quantum computing eventually break SHA256 or ECDSA secp256k1. With any luck, this would be gradual process (as with MD5 and SHA1), so that there is time for an orderly hard fork to a different digital signature algorithm or cryptographic hash algorithm. Then the UTXOs with lost private keys can either be formally destroyed as part of the hard fork or claimed by whoever first cracks them.
And as Saint-loup notes, if Moore's Law continues long enough, even brute force attacks might eventually compromise the cryptographic primitives currently used by Bitcoin.
you seem to be very educated. Do you know what is the probability to import an account with some money in it when a user enter a random private key? AFAIK, there are "only" 52^62 potential private keys. ie 52 characters in lowercase, uppercase or digit. Your numbers are off. A bitcoin address is an encoding using base-58. The actual number of possible addresses is 2 160, and each address is shared by nearly 2 94 private keys. thank you but I don't understand what "each address is shared by nearly 2 94 private keys." means... Each address is accessible by 2 94? When I export a private key from an address it only gives one private key to me.... Sorry, typo. Should be 2 96For every bitcoin address, there are nearly 2 96 private keys that are associated with it. That is because there are 2 160 addresses, but nearly 2 256 private keys.

The actual number of possible addresses is 2 160. Assuming there are 10 million addresses holding bitcoins (there aren't nearly that many), the probability of a new address duplicating one in use (a "collision") is approximately 1 in 2 160 / 2 23, or 1 in 2 137, or 1 in 174,000,000,000,000,000,000,000,000,000,000,000,000,000.

...this chat is like a cult where the higher ups are trying to not let new people get higher ranks, so they can keep the air drops for themselves for as long as possible. ...
Believe me, most people don't care about the airdrops or don't even know about them. Airdrops and signature campaigns are a newbie thing.

If my post is identical to 30 other posts that don't get taken down, that is the definition of being singled out, yes.
Sorry for being skeptical. Why do you believe that you were picked to be the single user whose posts get removed? There are over 1 million user accounts on Bitcointalk. Do you believe that you were randomly selected, or do you believe that the moderators chose you specifically?

I can't seem to find that address I was talking about. Now I will just use this example https://blockchain.info/address/1HB5XMLmzFVj8ALj6mfBsbifRoD4miY36vAs u can see this guy has 4025 total received of bitcoin, but only 7.5 btc for final balance. Where is the remaining 4017.5 btc I wonder. Could it be in his another address in his wallet or has he sent the bitcoin away by selling or something The remaining bitcoins were spent or moved to another address. There are over 500 pages of transactions. If you go to the 4th page, you will find some transactions that send some bitcoins from that address.

Bitcoin and the generation gap is natural. They will not understand it until they are forced to use it. Meanwhile the younger generation will be using it and learning it so if they don't learn and invest now they will miss out.
Then, isn't ironic that the older generation must teach the younger generation about Bitcoin?
