Mining on android smartphone is possible but not worth the time. There are two ways through which a person can mine on a smartphone.
1. Using apps that are able to mine cryptocurrency on the smartphone using its processor
2. Using multiple smartphones to build a mining rig and then mining cryptocurrencies analyzing it on a PC.

The first case is useless and won't give you any profits for the time you spend on it. It will also use most of your phone's power and will make it more prone to short circuit and a corrupt SoC. Apart from this there are only 1 or 2 crypto currencies that are smartphone mineable.

The second case is a little bit better than the first one and can generate smaller profits but then it is not match to GPUs and ASICs. This strategy was once used by Samsung where it use 100 samsung galaxies to build a mining rig to mine cryptos. But it is better to buy some GPUs and build a rig than to build a rig out of smartphones. If you have many smartphones lying around then that's a different thing.

Yeah that's true. Any number of persons can accelerate a transaction but the catch is that a transaction can be accelerated only a limited number of times within a specific time. For example the transaction on viabtc can be accelerated once in every hour. So any person can be able to accelerate a given transaction.
You are having a really bad luck since the Bitcoin network is congested at the moment. Only the transactions with much higher fees are getting confirmed. The current transaction fee is around 275 sats per byte. God knows when will your transaction be confirmed.

So if the payments are changing what are the new rates going to be ? Can you please update it on OP as well

Confirming that I received the BTC payment. Thanks manager

Most of the forks done are not having any major initiative behind their reason to fork from the bitcoin blockchain. The bitcoin cash fork did have the block size increase and is surviving because of the bid whales who have invested in it. The other forks are not worth and will not have any potential value in the future. There many upcoming forks which will be increasing the people's capital amount but most of them will be dumped as soon as people receive their forked coins. These forks are going to turn out waste of time as people will still continue to use BTC and dump the others.

It might be true that the money from altcoins is flowing towards bitcoin since the price of Bitcoin has increased massively within a couple of days bleeding out most of the altcoins. Altcoins have dropped approximately 20% in their prices. The surge in Bitcoin's price may be due to many reasons. The futures market opening on December 10 might have boosted the market trend. Investors from the wall street investing into Bitcoin might be another reason for the sudden surge as they would be investing big bucks. Altcoins will be having a tough time until Bitcoin spike high. It will take them a while to recover in their prices.

Lots of people in this forum are stating that Bitcoin is going to crash. How are they so sure about it ? Nobody can predict crypto accurately then why do you people spread negativity in the forum. The same topic "Bitcoin Crash" is being started many people in the forum. It will just create more of panic selling in the market. Stop spreading FUD and create a positive atmosphere in the forum.

Miners have mined more than 16 million Bitcoins and the supply is getting exhausted day by day. It is quite expected to see a spike in Bitcoin's price. As more investors buy BTC the ratio of BTC's growth will more likely increase. So we can't keep telling people all the time that the crash is incoming. There might be some corrections but then that is how trading works.

We may not call it a crash but a minor dump. Even if BTC dumps $1000 in price it will still be a minor dump since the red candle will not be that big when compared to green ones. What it basically means is that Bitcoin costs thousands of dollars now and even a small dump in the graph will mean cutting off thousands of dollars from BTC's price. So before the minor dump/correction takes place it would be wise to sell off some % of the Bitcoins to buy more later. It is always best to buy and sell small amounts of BTC and not selling it completely. Bitcoin has good potential and will eventually rise over the years. So selling it off completely is more risky as the price might boom anytime and leave you with regret.

Earning interest on anything for just keeping it as it is, is a great way to earn passive income. Freebitco.in offers 4.08% of annual interest in BTC for keeping your coins in their website. The interest is not that great as most of the pay banks pay the same interest and some pay more than this too.
It might be good in a way that the returns are in BTC which already is skyrocketing this year. Try searching for other websites which offers more interest than this for example Yobit Investbox which offers upto 0.1% interest daily which gives 36% annually. Although the investment amount might be high and the investment plan might not be that long but even if you keep it for 2 months it will be more than what freebitco.in pays for the whole year. I don't say freebitco.in is not good but there are better options.

I have accelerated the transaction 264dd9a129977cccc1cbae99f05b6d5ccd7a09bde012ad6ee35e99e126f994d9
You could accelerate transactions by yourself by visiting the free accelerating websites like confirmtx.com and viabtc . You have set the fee for the transaction ID 8841cfe96ead2d1351e381ac4438cf26f22572c133db1e8ab1904285192fb46f very low and that's why it has not been confirmed yet. The fee is just 1 sat per byte. Consider at least 90-100 sats per byte for any transaction. You should be more generous and pay the miners some additional fee for their contribution towards the Bitcoin network. This transaction was already been accelerated by someone else.

Bitcoin has been rising all these years just because of more demand and less supply. So if the demand goes down then the supply will increase by the people selling Bitcoin. In that case the price of BTC will keep on depreciating if there is no buyers left. Bitcoin can also crash if there are many unconfirmed transactions filled in the memory pool. When transactions will be delayed people will try to sell off their BTC. Increase in transaction fee might cause trouble to small investors and might become a major issue later on too. These issues are just assumptions and I don't want it to happen either. I <3 BTC  

Wallets are not service providers so that they can control over your Bitcoin. Wallets are designed for Bitcoin users to store their Bitcoins.
There are many mobile wallets in the appstore and playstore where you can download the Bitcoin wallets from but be sure that the wallet you download is safe, secure and has the ability to support the future forks of Bitcoin. There are good wallets such as Mycelium and Electrum which have been performing well and supports most of the genuine forks.

There are two types of miners who mine transactions based on their preference. Individual miners and pool miners. Pool miners are those who from a group of miners to build more mining power and mine transactions together.
They choose as many transactions as possible because at the end of the day they want to earn more and for that they have to mine more.
This depends on their preference as some miners prefer transactions with fees while other prefers more number of transactions. Both need the same amount of energy and can be equally profitable.
More number of transactions take more time. Quite logical.
Yes the miner can configure/choose which transaction he wants to mine and can set the software according to the given criteria. You must be knowledgeable with computers in order to perform these tasks.

Mate, I don't think what you are saying is 100% true. There could be some of the factors you stated as true but not all of them.
Chinese did shutdown the exchanges but the people did make use of the money in other places. Apart from that China is not the only country to supply Bitcoin. There are many other countries too. Though China is a huge contributor towards Bitcoin and the shutdown would have caused some spikes in Bitcoin's charts but reopening the exchanges wouldn't make much of a difference. The only thing I see is that the price will rather increase when China reopens Bitcoin exchanges as people would be filling their bags with Bitcoin. The mining part is a different thing now and can cause a minor dump in price.

Bitcoin can be considered as a bubble since it's price has been peaking every month and has grown 11x times in just one year.
This is a very fast movement when compared to the past few years. Such rapid growth convinces any expert trader to believe that Bitcoin's price is a bubble and it will continue to rise until it hits millions. I say millions becuase very few people in the world know about Bitcoin and as more people get to know about it, the more investors will start buying it. Until a point comes when no investor will buy it then BTC will start crashing.

China banned ICOs because many ICOs that emerged in the crypto market started to scam their investors and stole their money from them.
This was the main reason behind all the banning of ICOs in China. They shutdown Bitcoin exchanges because of security reasons as many investors lost their money China didn't wanted others to lose their money and shutdown the exchanges so that people don't buy BTC and encourage investing in ICOs. Apart from that they considered Bitcoin as not safe for payments and transactions and hence shut down the exchanges. They have started regulating them now. Bitcoin will start crashing when no more people buy it. This will take an eternity as there billions of people in the world and very few people know about Bitcoin yet. They will buy it when they know about it. May be people will forget about Bitcoin and know more about it as Satoshis since it will be so costly to afford a Bitcoin.

How do you plan on doing so? Is there any asset that signifies the blockchain itself. I think you don't understand what blockchain is.
The blockchain will be there even if every currency falls down because it is a network and not an asset/commodity. Blockchain cannot go down or up but it can only grow. It is a newtork where all the blocks that represents transactions are stored. Find out a good video on youtube that explains about blockchain and crypto currency before putting up any question like this.

The third point you said might not be really true. I do agree with the first two points though. Bitcoin did rapidly increase in the last month hovering from $6000 to a whopping $11500 now which is almost double the amount. You say there was not a significant pullback while you can see that 29th November the price was at the peak of $11250 and suffered from a huge pullback and dropped to $8750 which is a drop of $2500. Does this doesn't sound to you like a pullback. The correction has made Bitcoin much stronger now and Bitcoin has become stable now at $11500. The price might fall a little down but then Bitcoin recovers every time and who knows what 2018 will bring to us.

Clearly you have just assumed that Bitcoin will reach $100 million. The theory is incomplete since you have not mentioned the time it will take for Bitcoin to reach $100 million. Bitcoin has real potential and I won't deny that but assuming 1 satoshi = $1 is a little to much and won't be certainly possible seeing the current issues like unconfirmed transactions, network overload, high transaction fees etc... These are real problems without any reliable solutions yet. Bitcoin has to solve these problems first in order to reach the $100 million milestone.

Well that depends on the amount you are holding and if you have some extra money to spend. Hardware wallets are great for proper security but it adds cost to purchase it. If the amount you are holding in crypto is large enough that it needs such security then you should definitely buy a hardware wallet and ledger nano and trezor are a good choice for that. If you don't have a large amount of crypto then you should probably try some paper wallet or private wallet that you can download in your smartphone or PC and save the private key in a safe place.
I would prefer buying it if I have more than 1 BTC. I currently don't have that much and that's why don't have the need to buy one now.
