There is always a possibility of correction. I think another major correction in the near future is unlikely and I expect a gradual rise to about $20k with minor corrections (like 15-20%), but I may be wrong. Nobody can predict the price.

Today bitcoins (and other coins with the same SHA256 algorithm, like Bitcoin Cash) are mined with specialized hardware, ASICs (application-specific integrated circuits). They are orders of magnitude faster than GPUs for this task, so bitcoin mining with GPUs is essentially dead (and was so for three or four years). Basically there are two options:

- Get an ASIC miner. I do not mine bitcoins since 2013 and I have no first-hand experience with ASICs, so it is better to ask someone in the Mining Hardware subforum (https://bitcointalk.org/index.php?board=76.0).

- Build GPU rig for mining altcoins, which is no less profitable. The choice of GPUs (ATI or Nvidia) depends on the coin(s) to be mined. There are some websites for comparison, for example https://whattomine.com/, and the Altcoin mining subforum I mentioned before.

Well, at least this time the developers are going to implement replay protection.

I'll be happy too. I'm not sure if bitcoin can reach $1 million, and I'll probably sell most of what I have for much less. But I'll hold a little, just in case

I think with its current price of about $15k and daily trading volume of more than $10 billion bitcoin is far from dead. I've seen it falling from $30 to $2 in 2011. Then I thought it was dead - but I was wrong even then.

Airdrops are free, so all they require is your time. I would say that most airdrops are (nearly) worthless, but there are hidden gems that can give you good profit.

Mining bitcoin directly using GPUs is hardly profitable nowadays, and the gains would be minuscule anyway. It is better to mine altcoins and then exchange them to BTC or cash. I suggest looking and asking in the Altcoin mining https://bitcointalk.org/index.php?board=160.0 section.

The crash in early 2014, AFAIR, was considerably influenced by Mt.Gox bankruptcy. Now there is a lot of functioning exchanges, so at least this aspect of the situation is different. I doubt that there will be another 10x rise in 2018, but I also think that falling below $10k is unlikely. Return to $20k and rise to $50k is possible.

The official number is rather low, about 5%, but the real number of unemployed is higher. Moreover, there is a lot of jobs with very low salaries, so having a single job may be not enough.

It is not the main problem and not the root cause. The main problem and the root cause is the economic system itself.

It will not, and cryptocurrencies are not going to change this. The current economic system cannot function without credits.

Both are possible, but in my opinion $20k is much more likely.

I hope ALTCOM address in place of bitcoin address is OK. I used to have it in the personal text, but now I'm in another signature campaign.

So far it looks like 35-40% correction, which is not untypical for bitcoin. Remember, for every seller there is a buyer, and the volumes are large. It means that there are people buying a lot of coins. It gives me hope that this is just a correction and the long-term upward trend will continue.

I did not know that duplicates are allowed, never saw such a seed.


Well, my knowledge of combinatorics is a bit rusty, so I forgot to account for the set size. Still, even if there is a possibility to check 1000 combinations per second (and, AFAIK. key derivation and address check are actually much slower), checking all 1E24 combinations would require the amount of time orders of magnitude larger than the age of the universe.

There was a crash from $5k to $3k (40%) in September within just a few days.

I think there is a significant transfer of funds to Ripple, but it is not large enough to account for decline of all other top coins.

Nobody know for sure. 30% corrections are not uncommon, there was 40% dump in September (from around $5k to $3k), but it has shorter duration. Right now everything falls, bitcoin and all top altcoins. It probably means that large investors are cashing out, but I cannot imagine that they will abandon such lucrative market.Therefore, we will see another pump.

Bitcoin will not have any noticeable effect on unemployment, globally or locally. Unemployment is an intrinsic property of the existing economic system and cannot be eliminated without changing it.

The chances are very close to 0. The amount of calculations needed for this is incredibly large. Suppose you already know the set of 12 words, but not their order. The number of possible permutations is 12! (12 factorial), which is 479001600. But there are much more words used for seeds. A meager set of 100 gives the number of permutations of about 9E157 (9 with 157 zeroes), and only millions of them correspond to existing wallets.

Agreed, especially for large amounts - exchanges and online wallets are not secure enough. Electron Cash is an excellent lightweight client.
