The main reason probably is because BCH is nonsense. Anyone switching from BTC to BCH will lose in mid- and long-term.
The reasons for that are quite simple:

1) There haven't been any tests on how the whole network reacts to 8x higher blocksize. BCH didnt have any "big blocks" yet. There are currently at about 20-50 KB (!).
No considerations have been made that 8x bigger blocks mean 8x bandwith, storage and verification time is needed. So this may work out.. but it could also equally not work out and completely collapse.

2) An on-chain scaling is not scalable. It may be enough for the next 3-5 years. But whats next? Change blocksize to 16, 32, 64 MB ? If blocksize gets increased even more a lot of bandwith will be only
used to keep the BCH network alive. And additionally the verification time of one block will exceed the average time it needs to create a block. This will lead to extreme(!) centralisation, because only miner
with super computer will be able to verify the 'old' block and mine a new block before "standard" miner have verified the last block.

BCH is doomed to fail. Wheter it will happen when blocks reach 6-8 MB, or later on..
The only tangible scaling solution would be to add a second layer "onto the blockchain". Thats where the lightning network comes in play.

A standard (legacy) transaction has the following size:
count of inputs * 180 + count of output * 34 + 10 = 224 +/- 40 byte

With segwit tx's the size is composed of:
count of inputs * 148 + count of output * 34 + 10 = 192 +/- 40 byte

Generally, your TX will be 32 bytes smaller per input.


Generally fees are set in sat/B.
Since the only "fee-advantage" you have with segwit are the smaller transactions, you can just proceed with taking the same sat/B fee, and paying less.


Yes.

You can use as much wallets as you want. There is no threat or anything when using different wallets.
You should just watch out for any compromised wallets or non-trustworthy wallets.
I am also using 3 wallets. 1 Hardware wallet where i store most of my coins, 1 desktop wallet which is used for small amounts.
And a mobile wallet to be able to recieve/send funds when im not at home. But a mobile wallet shouln't be regarded as fully secured.
Android phones have a lot vulnerabilities, therefore you should be only storing small amounts on mobile wallets.

The point with zimbabwe is that you won't be able to get your Zimbambwe dollar out of the country.
Due to the high inflation and the big supply of this worthless zimbabwe dollar people their are exchanging their money for BTC.
With BTC they are able to buy things AND to exchange their money later on for any currency. But if they keep their ZWD, they only will bebe able
to buy stuff in zimbabwe.. but they can't exchange their money for anything else. Meaning if someone thinks he can make money with them,
selling them BTC and trying to exchange ZWD afterwards for USD.. this won't work.. you basically won't get your money out of there.

Forks (in this case: hardforks) don't change anything regarding bitcoin. It generates a new Altcoin with the same block history until forking block of BTC.
This Altcoin will have the same features as bitcoin plus the freshly implemented (like 8mb blocks in BCC).


Yes, its not possible to "break" the maximum supply because its hardcoded into bitcoin itself.
The only "option" would be to create a hard fork.. but this, as already mentioned, would create a new altcoin and would have nothing in common with bitcoin.

A paper wallet itself is not "shit". "Losing the paper" can happen with every wallet. The clue is to have multiple copys stored in different places.
Its all about having a backup in a secured place. A hardware wallet could also be "shit" when you lose your device and the stupid paper-thing which contains your seed phrase.
Paper wallets, together with Hardware wallets are the best (safest) way to store your coins long term. I don't see why someone would not recommend to use these.

Exodus can't really perform an exit scam. They are not in control of your private keys.
Your private keys are generated and encrypted on your local computer. They never touch the server.
The only thing coud happen is that their server goes offline. Then you won't be able to synchronise your wallet and won't be able to push transactoins.
But in this case you could easily just export your private keys and import them into another wallet.
Im not using exodus, so i can't really tell how they implemented security features. I would rather use a well known, trusted and open-source wallet to store my coins.

Your ledger gives you the option to choose whether you want to store your coins on legacy-address-format (Which is the original address format)
or on segwit-address-format (SegWit was implemented in a soft fork a few weeks ago).
You are free to choose which you want to use. SegWit has the advantage of lower fees due to transactions being smaller in size. 
Both of them are safe to use, so its up to you which you prefer.

There are no segwit blocks. And no, we don't have 2MB blocks.
You are talking about the SegWit2x fork which should have happened a week ago. (The 2x stands for 2 times blocksize (2MB))
Bitcoin already adopted to SegWit address formats, to make transactions smaller (Which leads to lower fees per TX, since fees are calculated in sat/B).
But there hasn't been an adoption to 2MB blocks. And thats good. On-chain scaling is no solution.

@OP: There isn't a good reason to delay the SegWit adoption. But as its with everything.. people don't like changing habits.
Look at IPv6 vs. IPv4 for example.. IPv6 is available for years now.. But 80%+ in Europe/USA are still using IPv4.. Just because they are used to it.

Well, first.. we don't know which airdrop you joined. Usually you get your tokens from the airdrop. Are you sure you filled all fields correctly?
There might be some "aidrops" which don't distribute tokens afterwards. Those are mostly just for gathering informations (like eMail, addresses, ...).
Thats the reason why you should use a seperate email for airdrops, etc.
But you can't really call it a scam, since you were promised free tokens. And if you won't get your free tokens.. thats definetly not a scam. The airdrop is just not keeping its promise.

You don't have to worry when blockchain.info does not load instantly. They have server issues quite often.
Generally this should not lead to a loss of any bitcoins. Its just their front-end which has problems.
But if you guys wan't to be in control of your coins.. you should not use an online wallet. If blockhain.info screws up, your funds are gone.
And if their server has issues, you can't spend any coins. There are a lot of light weight wallets, which aren't much bigger than a few MB's.
Security-wise its definetly advisable to not use a web wallet and use a 'real' wallet instead.

cd = change directory and \PyWallet is the standard path.
You have to replace "PyWallet" with whatever path you have installed your wallet into.
If you don't know where you instaled pywallet into, you can just search for it in the windows search menu.
After you have found out what the path is, you can then open it in the command line with cd to your path.
E.g.:

Then you can run step 4 in the pywallet directory.

Since the transaction already has confirmed, it can't be reversed/replaced/manipulated in any way.
The only way to get your money back is to contact the support and describe your problem. They have to either send you the money back
or to fullfill your order. But it may be the case tha the vendor "choses" to fullfill the order even if you don't want to anymore. Its mostly up to him,
since you agreed to his terms by ordering something. But for the next time ordering i would suggest to use https://bitcoinfees.earn.com/
to get a fee which will get the transaction through within a given time period. I'd rather pay 0.50$ more for TX fee than having the hassle of getting my money back.

Theoretically such a transaction could sit in the mempool of the nodes "forever". But generally transactions which won't be confirmed within a few days
or get broadcastet again, get dropped out of the mempool.
Generally, after a few days, the transaction will be removed from the mempool and your wallet shows your balance again, which makes your coins
spendable again via wallet GUI.

1) Honestly, i don't think paypal will ever accept bitcoin. Actually paypal has quite good reasons for bitcon not to get adopted too much.
2) It's hard to predict what will happen in the future. Especially with such a "new" market/system like BTC. But basically i don't think this will happen.
3) This basically depends on what your standards are. If you focus on privacy/pseudonymity then BTC is definetly already better than paypal.
If you are looking for fast payments with low fees.. paypal is (currently) better in this case. But with paypal you have to trust a company to keep your money.
4) Thats why BTC (for me) is better than paypal. I rather pay some higher fees and wait 10-30 mins, but instead i (and only i) am in control of my money.

First, to clarify:
Blockchain = a technology based of a "chain of blocks"
Blockchain.info = a company which has the word "blockchain" in its name.

Did you check if all of your words are in the BIP39 word list?
If they all are in this list.. then it basically should work with any BIP39 compatible wallet.
If some of your words are not in the list i posted above.. then the probability its a blockchain.info wallet is pretty high since they used non-bip39 mnemonic seeds in the early years.
You should probably contact the support of blockchain.info, describing your problem.

1. There were no bitcoins which could be lost because this TX is not valid.
2. You should learn to read. The post above your clearly mentioned it: That address has a private key generated with a secret exponent of 0.

I actually don't see why you wan't to create such a transaction. You won't be able to trick someone with that. This TX will get rejected everywhere.
But if you still want to create such a TX, then please read into it. Its not that hard.

You don't have to worry about your coins. You only can have 5 Apps installed at the same time.
But if you wan't to use another wallet at a given time you can just deinstall an app and install the one you wish.
Your seed stays the same. Therefore your coins also will remain "on your device". It doesn't matter if the app is on your device currently.
You can always just deinstall some apps and reinstall them later and your coins will still be there.
All you need is basically your 12/18/24 word seed. Your device generates addresses for every coin out from this seed.
As long as you keep it in a safe place, you will always have the ability to access your funds.

Creating a portfolio does not really depend on your capital. I don't think you will get a lof of serious awnsers to such a question here.
A lot of people will probably promote their own coin/token. If you are looking for a halfway stable investment i would recommend to look at
https://coinmarketcap.com and chose some of the top 15. I'd recommend to invest the most of your capital into BTC and maybe ETH.
But you should definetly keep away from Bitcoin Cash and from Bitcoin Gold. Those forks have been basically just created to scam people.
Those will crash pretty soon.

If you aren't able to import it into electrum you could first check if all of those 19 words are in the BIP 39 word list.
If every word is in the list (https://github.com/bitcoin/bips/blob/master/bip-0039/bip-0039-wordlists.md) then you should be able
to recover your coins in 'any' BIP39 compatible wallet. But if your seed contains words which aren't in this list.. then it might be
due to it being an old blockchain.info wallet. They used mnemonic seeds with words, which weren't in the BIP 39 word list.
You might contact the blockchain.info support for further information.
