I first found out about bitcoin in 2012 when a family member mentioned he was experimenting with cryptocurrency.

Since then I’ve been following bitcoin and some of the more modern digital currencies like Litecoin, Goldcoin, and Ethereum.

Hold them, for now. Watch the markets and see what altcoins seem to maintain their value when Bitcoin dips. Be ready to move into them. I wouldn't bother with third parties who will do things for you, as there's always a fee larger than Bitcoin transaction fees.

Your mileage may vary.

I shy away from absolutes, but I think its safe to say this will never happen in our lifetime. I don’t think there’s even a currency backed by a sovereign government that could suffice as a replacement right now, never mind a crypto-currency no one controls or regulates.

All currency is a matter of faith, and for the moment bitcoin will remain a fringe player. Will it continue rising in popularity? I think yes. But barring catastrophic government failures across geographies, there is no way it can approach even a fraction of the scale of the US dollar’s reach.

As others have already pointed out, Bitcoin itself is international. It is not an official currency, but an unofficial currency, payment method, value-exchange system (pick your choice).

However, if you are referring to bitcoin as an official currency worldwide assuming we let go of the existing state issued currencies we have, it is neither a good idea or a practical one. The world’s GDP is too large for Bitcoin (at current) to support it - even if all 21 Million Bitcoins have been mined.

I'm not sure if other digital currencies will deliver meaningful competition to bitcoin. It could happen, but the network effect and momentum that bitcoin already has would be hard to overcome.

Hatred might be too strong a word, especially if the criticism of religion (and I mean here organized religion, not any simple belief), opposing it and decrying its evils, can be demagogically conflated with hatred towards believers, a fallacious identification many use in order to create an emotional confrontation beyond facts, arguments and evidence.

So rather than "hating" I would say "strongly oppose". And some (or many) atheists oppose, criticize and expose religion for the same reason that many theists do. Belief or unbelief in a deity is not a prerequisite for being aware of the many wrongs and evils of religion, the hatred it induces in people and its sad results.

Atheism is a philosophical and rational stance: atheists cannot believe in any deity because of the lack of evidence on its existence. Anti-religionism or the criticism of religion is also a moral stance based on the harm that belief has on people's lives, on societies and on human dignity, on the worst teachings of religion and on the suffering both of the faithful (as in the case of children raped by priests) and of the faithful's victims (as in the massacres of Rwanda and the genocide by ISIS/Daesh).

A "belief in what isn't science" is not a good definition of religion. My love of Bach and  Hieronymus Bosch is certainly not science (at least as of now), but it is not religion. Mysteries to be solved by science are not religion, either. Religion implies the belief beyond reason of a set of preternatural statements, obtained through divine revelation and which are not subject to criticism and which are imposed upon the faithful and/or the unfaithful.

The top 2 things that should be kept in focus are:

Have a clear understanding on how the particular market works:
 If you are running a restaurant, research on the market where you fish for raw material. Controlling and acquiring the raw material market would be a good strategy for expansion, and for rolling out at competitive prices compared to others.

Understand your customers:
When you are building a product, you need to know who your customers are. You need to price your stuff accordingly, not too low, not too high -just the right kind.

The best thing I find about Bitcoins is that all transactions are transparent in the ledger, i.e. any transaction made by Bitcoin is recorded for all to see. You may not know the identity behind the transaction, but the transaction detail in itself is recorded for all to verify and view.

Islam is not a religion of hate. It is a pure religion and all about doing good and being patient. Islam is perfect, but Muslims aren’t. That’s why Islam’s image is not always good. Not all Muslims convey the message of Islam. There are many Muslims out there who have nothing to do with Islam, and they make a bad impression. There are many other Muslims, on the contrary, who truly present Islam and change that bad impression into a good one. It’s all about making the right judgement.

Paper money has its own uses which are hard to replace by digital currency or cryptocurrency. But the future of paper money is oblivion by plastic money. Nope, I'm not talking here about card - I'm talking about plastic banknotes (already used in countries such as Romania, Australia, etc.). Money notes cannot be totally replaced. There are still many countries where not everybody has access to internet. Therefore digital currency has long to go.

I dont think that there is any chance of war in recent times due to following reasons:

1. Devastating costs.
A 3rd world war is likely to deteriorate into nuclear conflict; the initial aggressor being subjected to almost total destruction. There's no way to 'win'.

2. Lack of capacity.
Compared to the global empires of the early 1900's, most countries have vastly limited war making capacity. e.g. At the start of WWII France had about 5 million troops, in 2012 they have about 350,000. Our capacity has shrunk because war makes less sense in modern times. 

3. Insufficient motivation.
The few nations with the power to instigate a war have no political will to do so. See how unpopular the US/UK governments became after their relatively meagre invasion of Iraq. Even semi-despots like Putin would struggle to incite their populace to war.

US accused Russia for hacking elections, but i dont think so that US elections were hacked. They hacked the DNC’s e-mail servers, then released thousands of e-mails.

That very likely impacted the election. But Russia didn’t actually hack the voting systems or directly alter the result.

Drinking too much can weaken your immune system, making your body a much easier target for disease. Chronic drinkers are more liable to contract diseases like pneumonia and tuberculosis than people who do not drink too much. Drinking a lot on a single occasion slows your body’s ability to ward off infections – even up to 24 hours after getting drunk.

Instead of investing bitcoin in any other commodity, we should rather hold it as bitcoin is an investment in itself. Bitcoin is not only safe but also a highly profitable investment. People are earning huge through bitcoin investment. Few of my friends have recovered their home and car loans too and are enjoying their bitcoin investment profit.

Anyone can use bitcoin with some knowledge about it. The problem lies with the limited use of bitcoins, various scams regarding bitcoins and less awareness regarding cryptocurrencies.

No i dont think so that Satoshi Nakamoto is an A.I. Satoshi Nakamoto is just a pseudonym. The creator(s) of Bitcoin don't want to be identified and as brilliant as their technology works it seem very possible that he/they are clever enough to remain anonymous.

If you look at it as Currency, it is difficult for an average person to understand it because it is different.

Bitcoin, being a different kind of a digital currency, it breaks down conventional thinking in many aspects. No central regulatory body. The concept of mining. The open-ledger (blockchain), the way miners are rewarded, how transporting value is determined by its packet size and not value, the hash rate, the concept of limited supply. The 100 Million pennies in a Bitcoin, etc.

Its difficult enough for people in the money space to thoroughly understand Bitcoin.

For a common person, its an overkill. Its like trying to explain the concept of TCP/IP, Networking, Routing, the Internet for someone who wants to use email.  Overkill.

Bit coins are great but it replacing cash is tough because it depends upon political support and how safe and secure people feel accepting and using Bit coins.

For the next 40 years Bit coins will not replace cash, government's will have to monitor the cash flows and ensure security which is a huge process and will have to be done in phases.

Use of Bit coins in the black market to purchase controlled or illegal products and services have to be stopped for the acceptance rate to increase.Also not many people are aware about Bit coins.

Moreover, bitcoin transactions need internet connection which may not be available everytime specially in developing countries .

Why should you use bitcoins? Why should anyone use bitcoins?

There a several reasons we use bitcoins -

1.Bitcoin is inflation free.

2.There is limited supply of Bitcoins, there will only be 21 million Bitcoins ever in existence, with the last one being mined in about the year 2140.

3.You can get attractive discounts on certain retail outlets and e-commerce sites, if you pay using bitcoins.

4.You can transfer you money (Bitcoins) to anyone across the world for extremely low charges, and without any 3rd party.

5.You can keep Bitcoin as an investment. Due to limited supply and ever increasing demand, the exchange rate of Bitcoins is bound to increase substantially.

Nope, I wouldn't suggest to invest in bitcoin at preseny. Not at this point of time when bitcoin is trading at more then $1000. It is over priced. If you want to invest in bitcoins, wait for a good correction that is expected to happen soon.

Good Luck!
