I think that signature and social media campaigns are the best and the easiest way to earn Bitcoins. You can make a decent some of money participation in signature campaigns.
Lending your Bitcoins can also help you earn a decent amount of interest and is very profitable.
Gambling is another way to make Bitcoins and it is the fastest way to make Bitcoins without any doubt but is very risky as earnings depend entirely on your luck.
Trading and investing can also help you earn a decent some of money but only if you understand the crypto market.

This is evident that bitcoin has come a long way since it has begun and has reached immense heights of success and popularity among people and it has lead to increased users through out the world. But still I don’t think that bitcoin will be able to replace fiat currency. Because firstly, fiat currency is way more popular than bitcoins and also has many many more users through out the world. Secondly, fiat currency is a stable form of currency and its value does not fluctuate often whereas bitcoin is not a stable currency therefore its value fluctuate a lot.

I think that you should buy and hold both of them simply because both of them have tremendous potential and both can really show enormous amount of growth in future. Ethereum being the master of all smart contracts is one of the world's most popular crypto and ripple on the other hand is based upon the idea of global value transfer and is partnering with many banks like uni credit. Diversification between these two can help you earn good amounts of returns for sure.

I think what you mean is Bitcoin has defeated gold in terms of price. It has become more valuable than gold but i don't think that Bitcoin has surpassed gold in terms of popularity and stability. Gold still is the most popular investment in the world and almost everyone on the planet wants to invest in gold. It is without any doubt, one of the safest and most stable investments in the world and it would take Bitcoin years to surpass gold in terms of stability.

The most important factor which i consider before investing is the IDEA and CONCEPT. I try to invest in projects which have a very unique idea and the idea solves a problem of the masses. I try to look for projects which don't face any competition or are way ahead of competitor.
The other factor which i consider is the team. Only invest in projects which have a very very strong and experienced development team as the team is the thing which will drive the projects to new heights.

I think that you should invest in civic and stellar lumens as i see alot of potential in both these coins and you can easily expect their value to sky rocket this year for sure. Civic is a project based upon the idea of identity verification with help of block chain and linens is based upon the idea of global value transfer. Both the products are very capable and you can easily earn good amount of profits if you invest in both of them and diversify your investment.

The altcoins i believe which will surely grow in the near future are-
1.civic - a unique project based upon the idea of identity verification with help of blockchain technology.
2. Verge -a coin based upon the idea of complete privacy whose transactions are completely anonymous.
3.siacoin - a project based upon the idea of decentralized cloud storage with help of blockchain technology.
4.litecoin - similar to Bitcoin but almost 4 times faster than Bitcoin.
5. Ripple - a project based upon the idea of global value transfer which has tremendous amount of potential to grow.

I think that monero is one of the better projects available in the market right now and i see alot of potential in monero. It is the world's first privacy coin whose transactions are 100 percent secure and untraceable. It has one of the strongest development teams which is very capable and promising. It is gaining popularity and if it continues to grow at the same rate, you can easily expect it's price to be above 1000$ by end of this year for sure.

The amount i generally invest in an ICO is the amount that i assume i am willing to loose as most ICOs out there are scams and you are most likely to loose your money when you invest in an ICO. I usually invest something close to 3000-5000$ in a single ICO.
You can eanr tremendous amount of returns when you invest in the right ICO but it is very difficult and challenging to find the right ICO. Only invest the surplus in the ICO, the money you are willing to gamble and loose.

The coins which i would recommend you to invest in are CIVIC, LITECOIN and VERGE as i see alot of potential in all of these coins. Civic is a coin based upon the idea of identify verification with help of blockchain technology. You can easily 5x your money if you invest in this coin by end of this year.
Litecoin is known for its quick transactions as it is almost 4 times faster than Bitcoin making it more usable.
Verge is a privacy coin which can really grow this year.

The ICOs which i would like to suggest to you are -
1. ICO telegram - it will surely be one of the biggest ICOs the world has even seen and you can easily expect a good amount of profits from investing in this ICO..

2. VICE - it is another good project which pays users to watch adult content and the project can truly revolutionize yeh adult content market.

3. Lunyr - it is one of those project which can grow to a level to give you almost 10x return within one year of investment or so.

I think waves is a very capable platform and the decentralized exchange of waves is way better than conventional exchanges but i don't think that waves will surpass ethereum and be the platform which will host most of the ICOs and new projects in future. Ethereum has one of the strongest development teams available in the market and the currently popularity of ethereum will makes sure that it will stay way ahead of waves. You can easily expect the price of ethereum to be around 5k$ by end of neat year or so.

I do prefer holdings of gold over bitcoin because firstly, gold is way more popular than bitcoin and has way more users than bitcoin so it is more in demand. Secondly, people trust gold whereas don’t trust bitcoin. Then gold is a stable form of currency and its value does not fluctuate whereas bitcoin is not a stable currency and its value fluctuate a lot. Gold also has a physical entity whereas bitcoin is just a digital form of currency. Then one does not need internet for transactions of gold whereas one does need internet for transactions of bitcoin.

Yes it’s true that bitcoin has defeated gold in terms of prices but still I prefer gold over bitcoin because firstly, gold has a physical entity whereas bitcoin is a digital form of currency. Secondly gold is way more popular than bitcoins and has way more users than bitcoin also it is accepted everywhere whereas bitcoin is not. Then gold is regulated by government whereas bitcoin is not regulated by any government. Gold is also a stable form of currency and its price does not fluctuate often whereas bitcoin is not a stable form of currency and its value fluctuate a lot.

Yes it’s true that bitcoin has helped many people to make money and become financially strong and leading them to being rich. This because bitcoin is a very good platform to make money as it provides various ways to earn money. Firstly, one can start earning by joining a signature campaign where he or she has to post on relevant topics and then they are paid accordingly. Secondly, one can gamble bitcoin where one can make immense amount of money but it also poses a great level of risk of losing. Then one can trade bitcoin to make more money.

Bitcoin has come a long way since it had started and has gained immense amount of users which is a result of its huge popularity among people around the globe. But still I don’t think that bitcoin will be able to replace banks from the world because firstly, banks are way more popular than bitcoin and has way way more users than bitcoin. Then most of the people trust the banks with their money and don’t trust bitcoin with their money. Then banks regulate the currency and make it stable making its value stable whereas bitcoin is not regulated by any bank or government because of which its value is not stable and fluctuate a lot.

No. I don’t thing that bitcoin would have been as popular as it is now if it’s price would have been stable. Since most of the people use bitcoin to make money and one can only make money in bitcoin because it’s price is not stable, so it keeps on fluctuating and has high chances of increasing in the up coming future. There are many ways by which one can make money using bitcoin. So bitcoin’a Instability has made it so popular and famous between the users. Bitcoin instability is its greatest weakness and its greatest strength.

No I don’t think that bitcoin will be able to replace dollar because firstly, dollar is a stable form of currency because of which its value doesn’t fluctuate whereas bitcoin is not stable and it’s value fluctuate. Then dollar is centralised resulting in increase stability whereas bitcoin is decentralised resulting in decreased stability. Then dollar is way more popular than bitcoin because of which dollar has way more users than bitcoin. Dollars are more trusted also than bitcoin.

Bitcoin has reached high heights of success but still I think bitcoin or any other digital currency can not replace paper money because, firstly, paper money is way more popular than digital form of currency which has lead to increased users of paper money than bitcoin or any other digital currency. Then paper money is stable form and is centralised currency whereas digital currency is not stable and is decentralised form of currency.

Now is the right time to invest in bitcoin because firstly, it’s popularity is increasing day by day between people. Secondly it’s usage is also increasing and all this is is evident from the increasing prices of bitcoin. So if one invest now then he or she can get high return back on the invested money as prices of bitcoin will further increase in the future as it has very high potential.
