Advantages: It is a decentralised digital asset which works without a central repository or single administration.
Bitcoins provide pseudo anonymity to the transactions happening. Makes them secure and untraceable.
The transactions are irreversible.
Makes international transactions much easier.
Disadvantages: Bitcoin is highly volatile. Hence affects those business which have accepted butcoins as mode of payment.
Transactions take a long time to be approved of.
Also bitcoin has not been accepted globally.

Bitcoin is one of the world's best known digital currencies. It is classed as a safe, appreciating, decentralised digital asset which has helped to aid its popularity as well its value. One of the key driving forces behind bitcoin's value over the years is the fact that Bitcoin provides increased ease and convenience when it comes to online transactions with the added bonus of security and the transactions are of pseudo anonymous nature.

I see Ethereum crossing the $1500 mark in the next five years due to the fact that it is one of the most preffered platform for posting ICO's. Although one cannot be sure about the future but ethereum has one of the strongest development teams and has a lot of potential to grow. You can expect a good amount of worth from it. I view Ethereum as an emergent yet malleable digital asset for IoT (Internet of things) because of the use of smart contracts and decentralised applications.

I think some of the altcoins such as Monero, Litecoin, Ethereun have a lot of potential to grow.
Firstly the speed of transactions of Litecoins is four times faster than bitcoins which makes it more preferable.
Ethereum has one of the strongest development teams which will help it in faster growth.
Monero is the most preferable market coin other than bitcoin as it is completely anonymous and the transactions are secure and untraceable.

I will suggest that Ethereum would be the best choice. Ethereum is the most popular cryptocurrency at present after bitcoins. Also with a market capital of 40 billion dollars it has one of the strongest development teams. Being one if the most popular cryptocoins available in the market right now, there are good chances that Ethereum will be $500 by the begining of 2018. It already has proven a track record of tested technical ability to handle programmatic crisis mid flight.

Yes, people have started believing in bitcoins. With increase in its popularity, the confidence, the interest in bitcoin is increasing. It can be seen by the fact that more and more people have started investing into bitcoins.
Acceptance by the big shppimg times, that will take time. I cannot see the same happening in the near future as bitcoins still have a lot of homework to do and achieve many things before reaching that platform and being accepted as mode of payment.

I think the bivgest risk is the prices would go down and you would not get the worth it momey for the bitcoins you are holdong onto. You never know about the future and it wouldn't be the first time when the prices would fall down and that to a great extent. In 2013 a drop of 73% was seen in the bitcoins price when the bitcoin bubble burst. And seeing the charts of bitcoin one caneasily observe the fluctuations in the prices. The chart is just like a roller coaster ride , it goes up and up and suddenly it goes down.
I think my best advice would be not to put all of your money into bitcoins and also have something else as a safe asset and not to completely depend on bitcoins.

Bitcoin and gold according to me are completely different assets. But yes even I don't think that bitcoin won't be able to replace gold atleast in the coming years. Bitcoin is a totally new and emerging  digital currency whereas gold has been there for years. People have sl much confidence in gold but the same can't be said for the bitcoins. Also there is the fact that theft from digital wallets are taking place by the hackers, so there always remains the fear for the digital wallets. However gold can also be used for various other purposes and bitcoin is only used as a holding onto asset by most of the buyers.

Yes, it is quite risky to turn all your money into bitcoins and also not a very wise choice. Bitcoin has always been unstable. The fluctuations in the prices are so much that it is like a rollercoaster ride. So you can never know when you could have a huge loss in it.
Also as bitcoin has started becoming so popular and it is decentralised, the governments start looking for ways on how to control it and when they are not able to do so, either they accept it or they ban it. But its volatile nature puts a huge risk on our savings which is our hard earned money.

There is a huge possibility that billionaires invest into bitcoins. But I dont think that all of them invest into it. I mean these digital currencies have emerged only into the past few years and that makes them a bit of a risk taling factor. One of the notable names such as Mike Novogratz said bitcoin to be one of the best investments of his life and alao said that he has invested 10% of his earnings into it. That makes it a huge factor. While other masterminds say that they find bitcoin a bit of a fickle as it is so volatile as its price are fluctuating so manh times that they don't find bitcoin a reliable source to invest their money on.

idea is the most important thing you should look out for. Look for projects with unique and promising ideas. These projects are sure to grow in future and can help you earn huge profits

team is another important factor to look out for as a strong team will surely help a project to grow.implementation of the idea is carried out by the team so team is important.

popularity of the project also matters as popular projects tend to grow quickly and are also able to raise handsome amount of money during the ICO. Money is needed in every phase of growth.

I would not suggest you to buy altcoins right now .bitcoin is showing tremendous amount of growth right now and we can still expect more growth from Bitcoin in the coming days.growth in price of Bitcoin is certain and the more Bitcoin will grow ,more the value of altcoins will decrease.
I think buying and holding bitcoins will be a way better option to ensure growth as well as safety of your principal amount.

BAT (basic attention token ) is one of the best newcomer tokens. It is based upon the idea of digital advertising and aims to make advertising more effective and affordable.this project can truly revolutionise the field of advertising. The team also consist of many elite technical developers like cofounder of Java.
This project has a lot of potential to grow and you can expect a tremendous amount of growth of this project in the coming years .

I think NEO and CIVIC the two coins which are capable of 1000 times growth within next two years.
CIVIC is a coin based upon the idea of low cost identity verification with help of block chain technology. The idea is very interesting and unique and the project will surely grow in future. The team of the project is also very strong..
NEO is one of the most popular coin available in the market. It is regarded as Chinese ethereum by many. The project has alot of potential and can surely grow in future.

Investing in Bitcoin is way better and safer than investing in dogecoin. Bitcoin is the first and the most popular cryptocurrency available in the market. It is the master of all cryptocurrencies including dogecoin. It is the cryptocurrency with one of the fastest rates of growth. It is the cryptocurrency with the highest acceptance.
Dogecoin, on the other hand is nowhere as popular and as stable as Bitcoin. You should invest in Bitcoin without any hesitations.

Verge is a coin which focuses on the privacy of the user. transactions are completely untraceable are very secure. The coin is completely anonymous and even the UP address of sender and receiver is kept private.
The development team of verge is also very strong and active which will also aid in its growth in future. You can expect the price of verge to be above 0.01$ within 2-3 years.

I don't think that bitxoim will be able to replace dollar anytime soon as dollar is still the most popular currency in the world as is regarded as global currency by many. Dollar can be used offline and no transaction fee is charged in its transactions. On the other hand, Bitcoin can't work offline and the high transaction fees makes it unsuitable for small transactions.
DOLLAR is supported and backed by the US government which makes it worldwide acceptable whereas Bitcoin is decentralized. I think that it will take Bitcoin more than 10 years to replace it.

The project seems really really interesting without any doubt. The idea of decentralized gaming can attract a huge number of people. This project can really appeal to alot of potential investors. The projects looks kinda simmilar to mobilego. The only major difference I was able to notice was that mobilego is a token and its a platform.
The thing unique to this project is the concept of proof of networking. Haven't heard any coin with PON configuration.
I would really like to have a look at the roadmap.

Litecoin is a coin in which you should surely invest. It is one of the most popular cryptocurrenies and it has a market capital of more than 3 billion usd. It is very promising as it is almost 4 times faster than Bitcoin as it has a block time of 2.5 minutes. The transactions in litecoin are lighting quick and the fees is also low.
You can expect it's price to be above 100$ by end of next year for sure.

My favorite coin would be civic. It is based upon the idea of low cost identity verification with help of Blockchain technology. The team of the project is also very strong and appears to be very promising. I see alot of potential in this project and I believe that it can show good growth in future. It has already grown 4 times its ico price within 120 days and you can still expect a higher value of it in the coming years.
