How did you reach in this conclusion? I really don't care, like many others, if is hong kong or everywhere in the earth this company. Every web wallet is no safe like desktop or hardware ones. Would be better read some things from the forum [General] Bitcoin Wallets - Which, what, why? or somewhere else as far as it concerns privacy and security of web wallets if you really care about the security of your bitcoins. 

I agree with your opinion and I would go with litecoin for several reasons; it's a cheap coin, very good confirmation time, it's be around from 2011 and so on. Moreover, people are willing to accept an altcoin there is no rush to convert it back to btc because they can use it for micropayments too. But if the blocksize debate ends maybe some kind of side-chains could be used for these small transactions. Till then we can use an altcoin like I said.

As far as it concerns all the relevant infrastructures (electricity, internet) will not be affected except the countries that will be involved in this war. On the other side and the bitcoin exclusively, then it depends from the rest countries. So, if there are people to give value and miners to include transactions in their blocks and secure the network even with many hassles bitcoin will not die but I have the sense the price will collapse so will have not to care about it.

I can understand that @OP wants to sell his ebook so as to earn some money. But it is not an ordinary one because it's a method how someone to double his money in 7 days. Frankly speaking if I knew a so reliable method I would have no reason to share with any other person. The main reason is that I am happy when I can advice someone to earn some dollars but at sure I am not willing to stop myself earning some money. So good luck with your ebook but would better to use amazon digital services like someone above already posted.

In my limited experience, I have two altcoins which I prefer more than others and for different reasons. First one is litecoin which I believe has some years after its creation (2011) with a devoted user base after the bitcoin one and some good features like as faster confirmation time than bitcoin and cheap so as it is appropriate for micropayments. On the other side I trust monero because had proven to protect the privacy and tractablity for every monero user.

I disagree because I cannot understand what has to do investments with gambling. Gambling is mathematically proof that in the long run the gambler will loose. I could say that is for fun with small amounts of money so as someone feels the excitement which gambling offers but after that is nothing. In addition, as far as it concerns lending, imo, is more riskier than trading. Maybe someone has to do its own research but how many scammers there are around who will not repaid their loan? So I believe is better to trade and loose your money because you did a wrong movement than somebody totally strange scams you and ask your money back.

This a quote from a well known sociologist and historian (as he claims) named Wallerstein. He was doing this question in other words at a recent thought on China China is Confident: How Realistic? In this article he refutes China's declarations; that it performs better in the world-economy than any other country else and the second one that it is growing stronger all the time its geopolitical position. Maybe I could agree for the first but at sure I won't with the second one which refers to geopolitical place. Moreover, I am skeptic because the particular scientist is known for his theories (anti-globalization movement)and certainly is not very objective.

Maybe yes maybe no. Taking me as an example my first wallet was a web one. Because nobody learned me anything about cryptocurrencies and that was the more easy way to store my first satoshis from faucets. After that I tested a mobile wallet only to check if it was appropriate for my needs but I gave it up because I had the opportunity to 'pair' my web wallet with my smartphone so it is more handy for me to control only one wallet in two different machines. At last, when I signed in this forum and I learned some about wallet security and reliability i went with desktop solution and now I trust most of all my desktop electrum wallet because I own the private keys and nobody else. As always security is not near with ease. You choose and get pros and cons.

For borrowers who get a loan for the first time I think about 30%-50% would be a sufficient collateral for you. Moreover, for reliable and honest borrowers after the third or fourth time they will ask for a loan, at your discretion, then the just smaller collateral about 15%-30% as a gift of good faith would be the more appropriate one.

As all of us we already know one of the very well known feature in bitcoin price is volatility which does not only depends due to trading in exchanges but from other factors like as the rejection of ETF. So even many people thought that bitcoin could crashed after the SEC disapproval we noticed that last days the price has stabilized in a satisfactory, with small fluctuations level,  about $1200 - $1250. But, we have also read the announcement from antpool mining pool about the BU support that could lead to different coins. This situation is very dangerous not only for nowadays price but in general for the course of bitcoin in the future.

From my point of view for all cryptos except bitcoin if bitcoin collapses then rest of all will not survive. Now, for bitcoin a possible nowadays danger is the increased disagreement between segwit and BU supporters which could lead to two bitcoins. That maybe is permissible for other coins like as ethereum but for bitcoin should be imo disastrous. Secondly a possible ban from many strong countries in the world so many users could forced to devaluate the coin. 

Assuming that you don't know that miners in order to include your transaction in their block they have be paid. So some of your money went as fees to them. But it would be better if you post the transaction id so as to see what happened. The only certain is that electrum does not charge you with fees. It's a completely free desktop wallet.

As many questions the answer is not black or white but it depends. So if you want other people to adopt bitcoin as currency then you have to ask it. That is, when you buy something you could ask if they accept bitcoin as currency. Meanwhile if there are many customers who do the same question and they try to find the particular shop who accepts this medium of payment then their desire is a demand; In this way the merchants are forced to happily accept bitcoin in order to increase their customers base. 

That can’t possibly be the case. The big picture for someone is completely different for another one. Can you find somewhere in the original paper of Nakamoto something like that ? You claim that poor people will not be saved by bitcoin but only rich ones. Have you ever thought that about 2/3 of world wide people are without bank status? How these people can accept or send money (apart from person to person cash)? Bitcoin gave anyone this opportunity without the need of any bank. On the other side bitcoin is a currency and a commodity like as gold. Does any of these two is free somewhere in the world?

Assuming that you see bitcoin as commodity the answer is obvious. Any amount of bitcoin is enough like as with gold metrics (carats, ounces). As we know there are many people in earth without gold but nobody wander if gold reserves are enough compared to world population. Moreover assuming that you use bitcoin as currency again I could say that is enough too. Even for 1 satoshi (10^-8 btc) if the need arises for less then you can convert it into fiat or an altcoin.   

In fact there is not such as an "innocent" service that pays someone with fiat to accelerate his transaction but an advertisement from Jihan Wu supporting the BU communication channel. There are some ways like as opt-in RBF feature some wallets have to speed up an unconfirmed transaction increasing the fees without the need to go with fiat. Here you go

Saving is not always the best approach and especially when speaking about bitcoin where volatility is an inherent feature. In addition, there is not only the price which fluctuates but the issue with the block size debate which may lead to a hard fork. Currently antpool switched their pool to Bitcoin Unlimited which nobody knows how this movement will influence not only the price but the course of bitcoin.

Unfortunately these are the worst news I could listen. Personally speaking, I do not care so much about the price as the future of the currency because people give value to bitcoin and not miners. I wonder under what logic Jihan Wu went into this decision. Obviously, if the price collapses money will be losen not only by the users but also from miners too because their operating costs are constant. Therefore, Jihan is very risky and played "all in" or is too sure that segwit supporters will not have time to react and finally will accept his movement. In addition, the publication of UASF played a significant role to antpool's decision.

The way I see it, when somebody is investor the basic rule is not all eggs in one basket. That is, even bitcoin is the leader of cryptocurrencies and till now has a brilliant course so it came here to stay but it is also volatile for the following reasons. First, there is a fundamental difference with fiat because a government and a central/national bank is behind of it so as to support it when the price is weaken. Moreover, is easier to be manipulated by some big holders than strong fiat when they try to liquidate it. In addition some events like as hacking to MtGox and Bitfinex, rumors about banning and strict regulations, ETF rejection so on are factors which seriously impact the price of bitcoin. On the other side I doubt if there is more promising currency or commodity in the 20th century.

I would like a scale from 0-100 but according to @OP preference I am between 3 and 4. I believe the potential of bitcoin but it is a technological innovation which the most people are not well informed and educated to understand its value. It's not easy not only for people in underdeveloped countries due to poor infrastructures and obvious problems of everyday surveillance but for the average Joe too. More people and especially the middle-aged ones are not willing to learn something so different and are scary to use it due to their fear of everything which is not tangible. The next or the one after that generation will be appropriate to embrace and incorporate into its everyday life the bitcoins usage.
