Yes, thats good and obvious. Demand of bitcoin increases day to day. People all over the world using it for trading and investment purpose. So its obvious that bitcoin accept by merchants, retailers and in hotels. These services must adopt for digital currency and it is todays need to accept virtual cryptocurrency in routine use.

In my view, you should go by second option, putting your eggs in different basket. That is you should invest in different altcoins, that will decrease your risk in trading and help to get better returns. We see bitcoin as future currency but altcoins also have furture in terms of growth and returns. Some altcoins invented for the purpose to build money for different projects. So by investigating about that projects you can decide where to invest your money.

For the first time I listened about bitcoin through my friend, he asked me " Do you know about bitcoin ?" and I replied "No ". That time he introduced bitcoin as virtual currency and its price in dollars. That time and still now I suprised that high value of bitcoin. That day I read about bitcoin and its history online. And luckily I got one book that explains me a lot about history, how to work and all other details about it.

Yes, bitcoin and altcoins are still profitable. Now a days bitcoins price gained so high, so it is hard to invest in bitcoin. But it is still better to invest in altcoins because they have better future, definitely their price will go high in next few days. So one can start trading in altcoin due to low price and take better returns on it.

No, bitcoin can't be used offline. It is a virtual cryptocurrency, so work on internet only. It is not present physicaly so how it work offline.
For all processing related to bitcoin, internet is required, up to start from mining, buying, transfer, etc all require internet. So internet require to complete all processess of bitcoin.

Yes, this is good approach for all. Now a days many people realised benefits and profits through investment in bitcoin. They realised bitcoin is good choice for better returns on their investment. They buy bitcoin to earn money as price of bitcoin increasing day to day.
This approach is good for bitcoins and bitcoiners future, as demamd increases value of bitcoin also increases hence will gives profits.

Yes, we have to think for this problem also. As Amazon started accepting bitcoin as payment mode, they already thinked on this issue, they may have solution on this also. As bitcoin transaction is one sided move, I think they can resend our order to correct problem.
But realy it will be better and faster than fiat currency.

Up and down in bitcoun price is depends upon demand of bitcoin in market. May be due to price fluctuation many people's selling their bitcoin and thats why down in price seen from ladt few days.
Other factors like regulations of governments and acceptance of bitcoin in routine exchange, also affect bitcoins value. As bitcoin is open to all, no one has control over it. So people scared to invest in it.

Yes, that is obvious. Because gold is traditionally the choice of investment due to its stable increasing value in international markets, it's physical appearance and governments control and regulations about it.
And as compared with gold cryptocurrency have no physical presence and no one have control on it, its value fluctuating all the times, hence high risk for trading.

In trading patience are most important factor. You have to maintain your patience when you invest and hold.  
To start trading it is always better to start with small amount, and then by considering trend and market behaviour increase the amount. Trading for long term is better than intraday, which is having high risk.

Whole world see towards bitcoin as a future currency, people do investment in it due to its increasing demand and acceptance in many countries.
There are many options available for investment but non of the option gives better returns like bitcoin or other cryptocurrencys. Other options for investment of money like stock market, mutual funds, gold, properties, etc.

There are many advantages of cryptocurrency over fiat currency. Out of that bitcoin having main advantage to make money. It's market price fluctuations help many people to invest at down. Also it is easy to handle, work on mobile and PC to make money, can be use to buy goods, etc. Also open to all hence anyone can work on it to earn money.

Cryptocurrencys and fiat currency are both have there own positions, both have there own uses. Fiat money is having physical appearance and controlled by respective regulations, so crypto can't replace it. Bitcoin is decentralised, open to all and doesn't have physical presence and only work on internet. So in future when people routinely use crypto, that time also fiat has its own position.

I think no, price of bitcoin will start to rise from this price. Bitcoin shows highest drop ever, but it will start to rise soon. In truth we can't predict what will happen with price in next days, but considering trend it may shows upword slope.

We can't exactly predict market value or price of crypto as it is depends on many factors. These factors determines market value, up and down of price. Some of them are like legalization of cryptocurrency by government, demand of coin, acceptance of coin by merchant and online retailers, etc.
We can analyse market behaviour on the basis of trend of values up and down and in dertail study of factors affecting it.

Yes, bitcoin is the savoir in many ways to peoples all over the world. It is Savior in terms of financial and mental conditions. Bitcoin help people to become self dependence and improved financial conditions by easy and fast way of earnings. Bitcoins main advantage is its decentralisation, so peoples all over the world work on it (easy to work) and make profit (work from any device with internet), and improved their lifestyle.

Yes, bitcoin is good choice for investment. In last few months price of Bitcoin increased drastically and now dropped with huge value, still it is good to invest in it. Investment considering risk of market is also important because no one can predict about market. It is good to start investment with small amount.

Yes, trading is unpredictable. Our profit or loss depends upon market value at that moment. We cant predict that value because it depends upon many factors.
In case of bitcoin, factors influencing market value are governments legislation of bitcoin and transaction fees offered for each transaction.

Social media perform main role at the time when bitcoins value gained height, that time social media spreads that news to all. In fact that time many peoples introduced by bitcoin. Bitcoins value messages spreads through social media rapidly and thats takes attention of people's. Due to social media people realises demannd of bitcoin.

Main reason to bitcoin is so expensive is its demand. Many Governments legalise bitcoin in routine use, merchants and retailers accepted it as payment mode and as it is open to all, whole world is using it.
People using it for trading, investment and for exchange mode, and thats create demand.
