I would probably advice you to invest in all three of them as all of them are very popular and have alot of potential. They can show good amount of growth in future and you can expect healthy amounts of profits from them in the long run.
BITCOIN is the master of all cryptocurrency and is without any doubt, the most popular of all cryptocurrencies available out there. It is the most stable and most widely accepted crypto available in the market.
LITECOIN for its lightning fast transactions and almost zero transaction fees. It is almost 4 times faster than Bitcoin as it has a block time of just 2.5 minutes. You can expect it's price to be above 300$ within 2-3 years
Ethereum is the most popular platform for hosting ICOs and new projects. It has a very strong development team and you can expect it's price to be above 1000$ within 1-2 years.
A diversification between all of them can help you reduce the market risks.

Most of the people are afraid of the highly volatile nature of crypto. The fear of loosing everything in one day makes them stay away from the crypto world.
The decentralized nature of cryptocurrencies is another factor why people hesitate to invest in cryptocurrencies. They believe that a thing not supported by government of the country will never survive in future.
Some people are also afraid of being scammed by some ponzi scheme or a shitty ICO as almost all ICOs are scam and it is very difficult to tell which project is legit and which is not.

I think that the Bitcoin gold network will go public in November and only then you can claim your Bitcoin gold. You would simply need the private keys to the wallet in which you were holding Bitcoin at the time of the hard fork on 25th October. You can claim your Bitcoin gold by importing your Bitcoins with help of your private keys in various wallets which support Bitcoin gold like Freewallet, Coinomi etc. Your Bitcoin gold will automatically be credited in your wallet after the network goes public on November 1.
For any further information, refer to the official Bitcoin gold website https://bitcoingold.org/.

I think ripple is way more popular and better than waves. It is a project based upon the idea of global value transfer and real time gross settlement. It is truly a revolutionary project which can change the global banking scenario. Ripple has been increasingly adopted by banks and is Used by companies such as UniCredit, UBS and Santander. All of this shows the enormous potential and daily usage ripple has got, you can expect the price of ripple to be around 1$ in 10 or so years.
 The payment transaction time is close to a few seconds which makes it one of the best choices for global transactions and found transfers.

Civic is a project based upon the idea of identity verification with help of block chain technology. Civic is basically an identity management service that allows people to protect and authorize the use of their identity. The services are also provided at very cheap rates and membership costs you very few dollars per month.
In future, you can expect civic to partner with various banks and credit card companies and you can expect a very wide use of civic in future
The team of the project is also very very strong and VINNY LINGHAM - the founder of the project is a very experienced technologist.

Yes, you can invest in various coins by buying them from various exchanges. You might face about of problem when you will get them exchanges for dollars, but i don't think that you will face any problems if you get them exchanges for rupees in India.you can simply cash them out in an Indian bank account and transfer the money into your us bank account.
And also there are some developers and projects who will allow you to invest in their ICO as these restrictions are put up by the developers only to protect them from the government procedures and allegations.

I would advice you to diversify your portfolio between popular and progressive altcoins like ETHEREUM, MONERO, LITECOIN and RIPPLE as these coins will surely grow in future and you can earn huge profits by holding them in the long run.
You can also invest some part of your investment in some upcoming unique ICO which you think can grow in future. I would recommend you to invest in XAURAM GAMMA and XENIO coin. Both of these projects can really grow in future.
.
Holding your Bitcoins is also a good way to earn profits as Bitcoin has alot of potential to grow.

Bitcoin is the master of all crypto and it is without any doubt, the most popular crypto available in the market.bitcoin has a lot of potential to grow in the future ans It is one of the fastest growing investments available in the market right now. they are hard to earn, limited in supply and easy to verify. With the increasing popularity and adoption of Blockchain technology, Bitcoin will certainly grow in future.
I think by end of 2018, a price of 15k$ is very much achievable if Bitcoin continues to grow with the same rate at which it is growing right now.

Litecoin is one of the good projects available in the market right now as it is one of the most popular altcoins available in the market right now. It is popular because it's transactions are lightning quick as it is almost 4 times faster than Bitcoin. The fee charges in transactions is also very reasonable.
The project has alot of potential to grow and i am expecting it's price to be above 300$ within 2-3 years.

Bitcoin is a very good platform for earning money because it gives many ways by which one can start earning money. Firstly one can start earning bitcoin by bitcoin mining. Then one can earn money by trading of bitcoins. Then on can earn money by lending them as a loan and can earn on the return. Then one can also enroll in a signature campaign where one has to post on relevant topics and then they are paid accordingly to the quality of posts. Then one can also earn via gambling of bitcoin although it is risky.

No I don’t think that bitcoin can eliminate all the banks from the world because firstly banks are more efficient than bitcoin. Then banks are way more popular than bitcoin among the people and because of which they have more users too. Then banks are available everywhere and easily accessible. And lastly banks do not need internet to run which is a big limitation of bitcoin. So because of all these reasons I don’t think bitcoin will be able to eliminate banks from the world.

No I don’t think that bitcoin has defeated gold as a total although it has defeated it in terms of price. This is because firstly  Gold is a precious metal and has a physical entity whereas bitcoin is just a digital currency. Then Gold is more stable than bitcoin. Gold is regulated by government or banks which increases its stability where as bitcoin is not regulated by any government which decreases it’s stability. Then Gold is more popular among people then bitcoin Because of which it has gained more users then bitcoin.

I would really like to invest my money in MONERO, LITECOIN and RIPPLE. All of these coins are based upon unique ideas and can show really good amount of growth in future. MONERO is based ion the ideas of privacy and the transactions are completely secure and untraceable. The price of monero will surely be above 200$ within 2-3 years.
LITECOIN is a project which is known for its quick transactions. It is almost 4 times faster than Bitcoin as it has a block time of 2.5 minutes.
RIPPLE is a project based up on the idea of global banking and global value transfer. Many banks have partnered with ripple and hence this project can show tremendous growth in coming years.

Bitcoin has come a long way since it had started and has seen tremendous success. During these years bitcoin has gained immense amount of popularity among the people which has lead to  increase in its users. But still I don’t think that bitcoin will become an international currency because firstly bitcoin is not stable form of currency and its value keeps on fluctuating. Secondly bitcoin is not regulated by any government which decreases its stability.  Thirdly it is way more less popular than the fiat money. Leading to limited bitcoin users.

Ethereum is a coin which has alot of potential and is the platform which hosts most of the new projects and ICOs. The team is strong and the project seems very promising but i don't think that ethereum will be able to surpass Bitcoin in the long run as Bitcoin is the master of all cryptocurrencies. It is the most popular crypto and is the most widely accepted crypto available in the market. I don't think that ethereum will be able to surpass Bitcoin as it is nowhere as popular and as stable as Bitcoin.

Yes I do believe that bitcoin reduces unemployment and makes people financially strong.  It ultimately leads the economy  to become more stronger. Bitcoin provides many ways for people to earn money firstly, one can   Join signature campaigns where he or she has to post on relevant topics and then they are accordingly paid. This is just like getting employed at a company where one has to devote his or hers time and energy and is being paid in return so ultimately This makes a person more financially strong and Provide employment leading to decrease in unemployment.

No. I don’t think that bitcoin is better than gold although it has achieved great heights in its field and is really successful and has defeated gold in terms of price. This is simply because of the following reasons. Firstly, gold is more stable than bitcoins so its value does not change like bitcoins. Then it is regulated by government so it is more stable whereas bitcoin is not governed by any government which decrease its stability. Then gold is a precious metal and has physical entity whereas bitcoin is just digital currency.

Yes. I do believe that its a risky option to put all your money into bitcoin as, it is not a stable form of currency so it’s prices keep on changing very often. It is not regulated by any government or bank so because of which also it’s value keeps on fluctuating and does not attain stability and also can result in collapsing. Also it is not that popular so because of which there limited users around the world. Then bitcoin is not trusted by many people so there are very few people who use it. Then many places don’t accept bitcoin. These are the main reasons because of which one should not put all in bitcoin.

Yes, it’s true that bitcoin helps people to earn money, become financially strong and ultimately become rich. This is because bitcoin provides various ways to earn money. Bitcoin is a very good platform to earn money. Firstly one can start earning money by bitcoin mining. Secondly, one can do bitcoin trading to earn money. One can lend money too. One can join signature campaign where he or she has to post on relevant topics and then they are paid accordingly. Bitcoin gambling is also a way but as its gambling so it’s a risky job.

Cryptocurrencies are doing really great but still I don’t think that they can make real money disappear. Because firstly, real money is way too popular than the cryptocurrencies. Which has lead to increased usage of real money than bitcoin. Secondly, real money is stable as compared to bitcoin because of which its value does not fluctuate often whereas bitcoin value fluctuate a lot. Then real money is regulated by the government which increases its stability and does not let it fail. Whereas bitcoin is not governed by any government so it decrease its stability and can fall.
