Agree, digital currency isn't just bitcoin but bank already issued their digital currency in form of cards.
Bitcoin created as an alternative currency but the difference is it's decentralized which makes it more interesting than any other centralized fiat currency. Doesn't mean fiat currency is bad at all but bitcoin is a better form of monetary system.
Bitcoin and fiat currency will be used in daily basis but it takes more time for bitcoin to achieve that goal.

Nice catch and this is why people shouldn't invest on shady coins which more likely to ended as scam.
New ICO and new project should proven their devs team and really legit to gain investors, but another factor to consider is whether the project or those coins will be profitable in the future or dead on arrival. Personally, I won't take a risk to invest precious bitcoin to random altcoins.

Well, you have been proven wrong because current price of bitcoin is over $3650 across global exchanges.
And we still have 10 days before segwit be activated, mean there are few days left before bitcoin reach $4000.
Look at bitcoin usability and development everywhere, in Japan which has the most - 'big parts' of support for bitcoin.
China exchanges and miners may have good effect to bitcoin as well, because Russia has been triggered to make the next biggest mining pool.

Indeed, segwit planned to be activated on August 21st and many people triggered to buy bitcoin, current price is over $3650 and OKCoiin has reached $3775. Increased in value while global markets such as US stock market has been sinking which may lead investors towards bitcoin. The majority of bitcoin trading volume seems occurs in Asia countries such as in Japan, South Korean, China and India. We're on bull run again, I guess. Another factor that maybe affect this rise is mainstream journalist from Bloomberg, the wall street journal, CNBC and New York times that have spread the positive news about bitcoin.

Market cap doesn't has significant effect to predict a coin price, nor does supply in circulation.
Volume in 24 hours may a good sign about how much people really interested to the coin.
But, avoid to invest on random coins without any usability or never rise again after fallen.
I prefer to buy some famous coins such as ethereum, monero, zcash or gigabyte even though the prices seems more expensive than other shit coins.

Depends on their age, kids around 7 years old could be taught about saving and bitcoin is the best way I guess, instead of using fiat currency which they could spend at their will. But it will be different if kids learn to save bitcoin for long term, even if they really knows about bitcoin advantages and the value keep increasing over time, then they should be happy about it.

Bitcoin price in every exchanges slightly different, and some exchanges price are higher than others, especially exchanges in Asia such as in Japan, South Korean, Indonesian, and even bitcoin rate in China exchanges > OKCoin has reached over $3673 right now.
Don't you know South Korean exchanges ever reached highest ATH in bitcoin history, over $4500 on May 2017 : https://www.coinspeaker.com/2017/05/25/bitcoin-price-hits-4600-south-korea-currently-trading-2717-globally/
Well, since segwit will be activated on August 21st, should affect bitcoin price, hopefully bitcoin could reach $4000 in this month.

First of all, where do you live man? There are many types of Bitcoin ATM, which some allow you to withdraw cash and others just allow you to convert cash into bitcoin without withdraw feature, usually depends on the size of the bitcoin ATM.
There's no a physical coin obviously . Due to confirmation time that takes 10 minutes - 1 hour, more or less, you should wait until it's confirmed before withdraw allowed.
Here a good video about withdraw cash through bitcoin ATM : https://m.youtube.com/watch?v=xMA_IefqIG8
If you want to try those machines, make sure to record a video about it, maybe could help others.

BCH supporters trying to lift up their token, but still can't rise more than $400 obviously, because people still have plenty of free bch in their stash, ready to sell it as soon as its price increase to certain price such as $300-$350-$400. There's no chance for bitcoin cash right now, maybe if bitcoin segwit2x fail in November or mining bch more profitable than bitcoin, then bch could reach more than $500-$1000 again, and at that time, I will sell mine

Honestly, I don't think miners or majority hashrate will switch to bitcoin cash, bitcoin segwit or segwit2x are better than bcash according to the nodes and business acceptance. Bcash will rise, maybe in one or two months later but the situation will be the same, people will sell bcash to convert into bitcoin, there will always one bitcoin, not 2 or 3.

Build some business with an announcement : Bitcoin accepted here in order to support bitcoin as a currency, to make people familiar with this digital currency and easier to spend it directly in retailers and merchants obviously.
Bitcoin acceptance in every country and city are different, so we have to create or convince more people and business owners to learn about a better monetary system which decentralized and free from central bank system.

There's nothing wrong about market cap as it's just a result from coins price and amount in circulation.
10 billions bitcoin çash market cap come from amount of this coin in the market/people hands and its price that at that time maybe around $650. But look at current price of bitcoin cash at $275 and the amount in circulation is 16,487,425 which mean its market cap is $4,548,682,708. The most important thing that affects market cap is the price of every coin, and the same thing goes for bitcoin.

Bitcoin worth more than cash value obviously, but we can't buy bitcoin according to market price and sell it to someone over the market price, simply because people will consider to buy bitcoin on exchanges or people who sell it for a cheaper price.
However, we don't have to do that because bitcoin value keep growing over time, all we have to do is waiting for uncertain time to sell bitcoin at higher rate, if you want to.

We're going through the way to activate segwit but the second step of the New York agreement is 2Mb hard fork, as core developers don't want to support 2Mb block size limit and have planned to develop bitcoin core 0.15.0 that will automatically disconnecting any network node which runs the segwit2x fork. Then we will likely have a chain split sooner rather than later, it would allow more freedom for people to choose the best proposal of scaling solution.

Yes, I mean the generated address which I will send btc to this Address (e.g. btc to eth), the generated address : 18vcXevhkaqbWxkoD****kH4KQxAY5HPLz is belong to SatoshiDirect?
And whenever I send bitcoin to this Address, instantly convert btc to ETH? Send to my eth address, of course.

My last question refers to, those ETH which will be sending to my eth address, come from your wallet (SatoshiDirect), right?
And, what's the guarantee that I will receive ethereum for my bitcoin? No offense.
I mean, everyone have to proof their service as a good one and trusted obviously.

May you point out some reasons why people should use your site to exchange altcoins? Instead of just using Poloniex or Bittrex services. And how much minimum transaction amount to exchange e.g. bitcoin to eth? Since people will lose their coins if the transaction is lower than the value, what kind of value?
Oh, I get it 0.00131509  BTC per transaction, to exchange btc to eth. As long as people know about it, then it's fair.
Last question, this address that will be generated > is it your address or what?
I don't want to risk my bitcoin to send it to the generated address (no offense), but all those coins which people want to exchange, come from your pocket/wallet?

Since there's no regulations about it, there's no way we can track this behavior especially from exchanges itself.
I mean, exchanges could get pretty huge profits by doing this spoof things. It's a common problem from the beginning as they are who have invested in bitcoin in the early development > have so many bitcoin or so much money on their pockets (whales) which could easily manipulate market price by doing it together. However, I believe that bitcoin users have been used to this behavior and anyone could get money from them (whales) if they do a mistake.

Quote for reference,

Lol   I am wondering, what's the point to regret ; if I did invest on bitcoin in the first place??
But, I get it now, yes, it's not so important but could influence people's minds to think what if I invest right now, and I could be a millionaire maybe someday in the future, maybe it takes 10-20 years but it's worth I guess.
The point is, to believe in bitcoin as it has been proven all this time to achieve unbelievable value and its potential still waiting to be revealed. It's not too late, as we're still in the early phase of bitcoin development and there are many countries will regulate or support bitcoin economics in the next few years for sure.

I still believe that segwit2x is a bait to activate segwit and core won't support 2Mb hard fork obviously, and we don't know yet, how many miners will support this hard fork or how long it could fulfill the threshold. Segwit2x or 2Mb hard fork has been scheduled to take place in November but Bitcoin Core 0.15.0 will automatically disconnect nodes running Bitcoin ABC and the segwit fork. So, the answer is, hard fork unlikely to happen. Or, maybe I am wrong about it, let's see what will happen in November.

Woow, it's a big news
Russia want to develop their own mining system to challenge China, doesn't mean bitcoin mining become centralized as it can't be as long as there are some sides compete to process the blocks. It just added another Power in bitcoin mining, balancing and stabilize between bitcoin miners.
And I guess it is a Big ICO as well, where I can invest? What's the site to invest? Look at the opportunity, 18% of their earnings is a good deal. The initial coin offering (ICO) for these “RMC” tokens will provide holders with rights to 18% of the earnings generated by all mining equipment purchased with investment funds.
