Thanks!

If a miner recieves two transactions with the same sat/B fee it depends on the algorithm he uses for including transactions into a block.
Usually miners are looking for the biggest profit. For example: If a miner already included the "few" transactions with the highest fee and now
only has, lets say, 200 Byte left in this block. Then if TX A is 100 bytes big and TX B is 300 bytes.. he will either confirm TX A into his block or he skips A and B
and confirms TX C with a lower sat/B fee, but a bigger size so the "overall-"profit is bigger. You can't tell for sure how a miner decides on 2 (exact) same transactions.
Its all how they have coded their algorithm. I think if there is no monetary advantage most miners will go with FIFO.

Yes, full replay protection has been applied. There is no risk in claiming your BTG now.
Of course, this requires a non-malicious software/wallet which you will use to "claim" your BTG.

Personally, yes. I would always move my BTC out of the wallet before importing the private keys into a different software.
Those 5$ transaction fees are nothing compared to the (potential) loss of all of my funds.

Moving your BTC out of your wallet first is probably the most important.
You should be careful which software you use to get your BTG. Only use reputable and (if possible) open source wallet which has been reviewed.
There is always a risk with malware hidden inside a wallet software just waiting to get access to your private keys (either BTG, or in most cases: BTC).
If you are "splitting" your coins with security in mind and you are using your common sense then you can consider it safe to "claim" your BTG.

Depends on what you mean with "any kind of coin". You can look at stakes as a "ratio" of coins you will get.
To be exactly 1 stake conforms the ratio of 1/(Amount of shares circulating). If you get 50% of all distributed stakes, you will get 50% of all coins (which are bound to this offer).
So, yes, you can use stakes for any ICO, altcoin or anything you wan't to offer to people.

This question is formulated pretty universally.
Bitcoin itself (the blockchain, the software itself and the transactions) can't be hacked or manipulated in any way.
But any 3rd party software, theoretically, can be manipulated. Your PC also can be "hacked" (or better: infected with malware).
This could lead to your btc's being stolen (depending on how you store your coins).
BTC is also quite often used in frauds. Look at all the ransomware around. They collect payments via BTC, because it has those beneficial features.
But as long you store your coins right, and use your common sense with a pinch of security in mind.. your coins will stay safe and can't be stolen or "hacked".

I am focusing on coins which are most promising (to me).
Those are BTC (mostly), ETH and XRP (I hate the idea of ripple, but i see it becoming popular in the future due to its featues
attracting banks and big whales. But im probably gonna sell all of them when i think it gained enough profit).
And im looking forward to finally invest into verify. IMO this ICO has a big potential since it solves a lot of Buyer/Seller problems (For more Infos you can check my signature).
But im definetly keeping myself far away from any scam shit altcoins which are basically just here because some "devs" want to gain profit.

I don't see those forks from the original bitcoin chain as a blessing. Those hardforks don't bring any confident advantages.
BCH is just taking bitcoins hashrate because miner switch betwen those 2 chains, aiming the biggest profit.
In addition to that those shitcoins will later be pumped and dumped. Take BCH for example. It got pumped last week, before dropping again.
The same will happen with BTG. Especially with the premining phase of 8k blocks. This results in 100k free BTG for the scammer devs of bitcoin gold.
Those will be pushed on the market after a pump resulting in a big profit for them.. and in a big loss for every user who was naive enough to spend money on such a shitcoin.
IMO this just brings bad reputation to cryptocurrencies over all. At least BTG doesn't use the same mining algorithm as BTC/BCH do.

Ripple is far, far away from being decentralized.
Actually its a startup with offices in San Francisco, Sydney and NY.
They have full control over their ripple network, and therefore also over XRP.
Ripple is aimed for banks to make payments faster, easier and cheaper worldwide. But its mostly intended to be used by Banks.
Banks might use XRP in the future to transfer.. but this doesn't directly mean that the price of XRP will rise.
Banks have the opportunity to buy XRP directly from Ripple. No need of an exchange, etc.. So there is no guaranteed price swing coming.

As far as i know bittrex made a statement about BTG a few weeks ago.
They stated that they will give their users who had BTC on their exchange, at the moment of the fork, will be credited their BTG.
And additionally i think i can remember they stated to not open a trading pair with BTG. Because BTG is no "digital asset".
Its more like a scamcoin with its premine of 8000 blocks (thats 100.000 BTG). Perfectly made to make money with other peoples stupidness.

What exactly do you mean by guessing "password and peers"?
Your government has no ability to steal your coins. Doesn't matter which government you are talking about.
Yes, secret authorities are in charge of 0-day exploits.. but none of them cares about your coins.
You probably got a malware somehow to your pc. It may be due to a cracked windows version.. those mostly are infected already.
Or you may plugged in an usb stick which was plugged in on another machine already? This is also an possible way of infecting your pc.

I would recommend you to read the article. You won't be able to "pay bitcoin with mastercard".
Its about the blockchain technology itself. An patent which has been submitted from MasterCard.
It, itself, has nothing to do with bitcoin. Its just an blockchain based payment system.  Thats pretty cheeky from mastercard..
This probably still will stay centralized and there aren't that much advantages of having a blockchain based technology which is not decentralized and spread around.

I dont think this is a good idea since addresses should be generally only used once. And additionally this leads to centralization of mining.
Big miners get higher probabilty of mining the next block.. thats a catch-22.


Thats basically like the first point? I don't see a considerable difference. Leads to centralization and not the way bitcoin is intended to be used.


There is nothing which speaks against miners who mine on different chains simultaneously, as long as its PoS.

Its kind of hard to get miners stop switching from BTC to BCH mining and vice versa. The easiest way would be for one currency to use a different algorithm.
But since BCH follower think its the "real" bitcoin (until it crashes to 10-200$.. which very likely will happen) there won't be any updates to mining algorithms.

If the address you imported as watch-only address, never was part of your wallet.. this means you also never had the control of the private key of this address.
Without a private key you are not able to spend bitcoins. Do you remember why you sent it to this address, even though it wasn't part of your wallet?
Did you maybe use another wallet software which generated this address?
The 1 BTC is still sitting there.. so this address is probably not in control of another person. Where did you get this address from?
I can't imagine you just blinly wrote down a valid address to send your coins? Maybe mobile wallet? Or did you ever print a paper wallet?
If you really can't think of any other wallet software and you already imported all your private keys.. i think the chances of getting your btc back is pretty low.
At least not without blockchain.info helping you.

In my opinion ether is better for online payments than LTC.
Ether is far more adopted than litecoin. And additionally your funds are faster credited, on average.
I, personally don't hold LTC. I am using ether for payments whenever btc doesn't suits due to network congestion, etc..
But there are no points which would speak against the use of litecoin for payments. Its personal preference.

This Incident can't be reproduced on bitcoin.
The bug found, causing to a loss of 300 mln $, was not a bug in the ethereum code itself.
That was a bug in an app which sits on a layer above ethereum. To be exactly this happened to a parity wallet provider.
Thats comparable to an online wallet provider for btc wallets which has an open exploitable vulnerability. This does not harm bitcoin at all.
Its only the mistake from the provider of this DAPP. By the way, this bug already has been published few months ago.
But the service provider of the parity eth wallet did not care about that. Now they get what they deserve.

Theoretically, yes. Private keys could be generated "a second time". This is called address collision.
There are 2^160 possible addresses which can be generated. Since, in theory, you have to search 1/2 of the search space to find a collision (birthday paradox),
you would need to calculate 2^159 priv-/pubkey pairs, on average, to find a collision by an address being generated a second time.
2^159 = 7307508200000000000000000000000000000000000000000000000
So the chances of a collision are almost zero. It is considered to be "bullet proof"

Provided the wallet you are using is using a good random number generator (with enough entropy).

Transactions with low fees will certainly get relayed. There may be a few nodes which specify which transactions will be relayed.
But the majority of the nodes relay transactions "whatever" fee they include.
Miner are profit orientated. Of course they can include a low fee tx instead of a transaction with a high fee.
But thats lost money. Miner usually include the highest (sat/B)fee transactions. Simply because it gives the most money.
But you are right, TX can be accelerated for free and thereby included by a miner (as a gesture of goodwill).

Generally brain wallets are always a bad idea. Humans can't generate a random password or whatsoever.
It might seem random to you, but in reality we are far far away from being random when generating passwords.
The pseudo-randomness in a human-generated password is only a fraction of the randomness of a pc-created password,
estimated enough entropy is gathered. And if you start using phrases which you can memorize easily, then it will be
pretty "easy" for an attacker to guess your phrase, if the amount of btc's stored is high enough.

For the sake of completeness:
A transaction, theoretically, can be double spent after it already has been confirmed.
This, of course, needs quite a big % of the computing power of the network (PoW) and a bit of luck (depending on the computing power) to success.
In an aimed attack its even possible to "sacrifice" 1 self-mined block to "fake" 1 confirmation of a TX. This can be made without the TX getting confirmed "on the real network".

Your 20 Sat/Byte fee is very low. You can use https://bitcoinfees.earn.com/ to check the current status of the network and the fee you have to use to get your
transaction confirmed within X blocks.
Normally your wallet should show your transaction.. even with a low fee. Maybe it didn't got broadcasted?
You should give us your transaction id. That makes it much easier for us to comprehend what happened.

Did you already check your TX on a block explorer (e.g. https://blockchain.info/ ) ?
Is the reciepent address the right one (the one you own)?

There are quite a few malwares around which replace a btc address you copy to your clipboard with theirs.
If that would be the case and your transaction goes to the wrong address, you should try to double spend it pretty quick (fortunately a low fee gives you more time).
I don't want to give you a fright. Just mentioning all options. The best for you would really be, if you'd give us the TX ID.
