I'm a student as well and i don't recommend you to invest into cloud mining instead just hold your bitcoin and wait for it's price to increase because you're gonna need to wait a long time before you're able to get a profit from it. (But i guess i'm a little bit late to tell you that.) Also i don't recommend you to trade bitcoin unless you have enough knowledge about trading because trading it's not easy, many people said that they earn profit through trading but it's not as easy as 123 but there's many things you need to consider first in order to start trading such as (Capital, Strategy, Different Plans and Good Decision

There's a lot of things you can do in order to earn bitcoin without investing money you can start here in the forum by joining different jobs such as:
- Signature Campaign
- Social Media Campaign
- Bounties
- Translations
- And you can offer services here in the forum such as designing, managing campaigns, escrow etc.

All of the things i stated is just an opinion it's up to you if you're going to follow it or not.

First of all investing to somethings doesn't mean that you will earn a profit, there's a high risk you're going to face whenever you're going to invest to something. So the both strategy is profitable but there's always a risk present in trading, so invest only what you can afford to lose. And it's not guaranteed that this strategy will work always, It depends also on the coin in where you're going to invest so you really need to study the coin first or analyze it before start trading.

LONG TERM INVESTMENT
Where in you're going to hold your coin for a long time and you'll withdraw it once you've reach your goal time/price.
High Profit
High Risk
Coins: Bitcoin, Ethereum

SHORT TERM INVESTMENT
Where in you're going to sell your coin once you've earn profit no matter how big or small it is.
Low Profit
Low risk
Coins: Ripple, Litecoin, Dash and other altcoins

You're right. There are some people in the trading platform who doesn't know what they're doing or maybe they have their own reasons why they're selling their bitcoin when the price drops so here are some of the reasons i know why they're selling their bitcoin.

1. Panicking - They're panicking about their lost. This is the most common mistake of the newbies in the trading platform they're panicking and selling their bitcoin when the price drops.
2. To cut their loses - They sell their bitcoin to cut their lost. They don't want to lose a large amount and choose to sell it right away while the price is dropping low.
3. They don't have enough knowledge - They don't have enough knowledge about bitcoins price, If they don't research about bitcoin they will think that it will not going to recover. And ending up selling their bitcoins.

All the reasons i stated comes from my observation, threads i read and my own experience.

There are 3 things you can do after receiving tokens, bounty stakes, airdrops, etc. The list below are the 2 things you can do after receiving your profit or your stakes you get from working in bounty campaigns.

Before you can do this 2 things you need to wait for the token or the coin to be in exchange first. So here are the 3 things you can do after it is listed on a exchange:

1. You can instantly sell your tokens to any kind of currency available in that exchange and earn profits.
2. You can hold and wait for the tokens price to increase its value and sell it.

so it's all up to you whether you're going to hold the token you've got from the bounty campaign or sell it right away to secure your profits. Just make sure to be responsible in every actions your going to make.

Of course you can start with trading small, actually it's the best way to start trading (But don't expect to get high profit.) why its the best way to start entering cryptocurrency trading? As I've seen about you, your just about to start cryptocurrency trading its the best way to start trading with a small profit not for profit but for the knowledge and experience you use the small profit to be familiarize how the trading works and how different kind of strategies in cryptocurrency trading works.

Remember that small amount = small profit/small lose. The higher your investment the higher your profit but the higher the risk also. Remember that trading is not easy and safe you should take responsibility on every actions you're going to do in trading so invest only what you can afford to lose.

Actually it all depends in my mood and in my guts, usually i just follow my guts in what kind of strategy am i going to use. Let's say about 2 months ago a bought a certain coin and i used the most common strategy the "Buy low and sell high" strategy where in i will buy a coin and once i earned at least 10%-15% i will sell it automatically and after that i tried to buy coin and used the day trading strategy and right now i'm really tired of watching the price goes up and down from time to time and i decided to do a long term investment.

So to summarize on how I do trading, I just use different strategies not to earn but to have fun, earn knowledge and experience by using different strategies in trading. The good thing about how I trade is that there's no pressure about on what am i doing since it's for the sake of experience and knowledge. (The profit is just a bonus)

Both platform are profitable but there's a big difference here, If you're looking for a work that you can earn in just minutes but is risky you should choose trading but if you don't have capital and want to earn bitcoin then choose signature campaigns. So here are the advantages and disadvantages of each platform:

TRADING CRYPTOCURRECNY
Advantages:
- Can earn in just minutes.
- Can take advantages to pumps.
- There's a lot of coin to invest in.
- You hold your time

Disadvantages:
- Needs capital
- Risky (Since we don't know what will happen to the market price)
- Needs skill, strategy, experience and knowledge about trading.

SIGNATURE CAMPAIGNS
Advantages:
- Can work without investment
- You hold your time (But needs to achieve min required post)
- Sure income

Disadvantages:
- If the manager runs.
- If didn't complete required min. posts.
- There's a lot of users nowadays and it's hard to find open signature campaign that pays BTC

There are things I/we need to consider first in order for us to trust a new altcoin but first want to let you know that even though you've met this requirements there's no guarantee that the new altcoin is trustworthy because some of the altcoins that is trustworthy becomes scam at the end so the things is that you really need to face a high risk whenever you're going to invest in altcoin, so keep that in mind. So here are the things I/we consider for us to trust a new altcoin.

1. Background of the team (If the team didn't give info about themselves then it's a little bit shady, but it doesn't mean that it is a scam... but there's a high chance that it is a scam)
2. Professionalism of their works such as, their official website, ann thread, social media accounts, etc.
3. Read their whitepaper and look if it's gonna happen or is it a good concept or just a promising words.
4. Check the roadmap if and other technical details
5. Do your own research.
6. Find an active and thriving community.
7. Look for special proof and validation.
8. Trust your guts.

So here are the things I consider before I trust the altcoin but it doesn't mean that it's 100% legit and trustworthy. Check this links to avoid ICO scams and how to avoid it.

There are different ways how are you going to convince people to invest in bitcoin, here are the things I already did in order to convince people like my schoolmates, relatives, local citizens that lives here.

• Show to them some proof of my profit.
• Show the chart of the bitcoins price, show to them the bitcoin price in the past few years and todays price.
• Give them knowledge about the cryptocurrency, blockchain etc.
• Explain to them how are they going to earn with just internet, phone/pc.
While convincing people to invest in bitcoin start with just a normal conversation and tell to them that you're earning a profit just at home and of course they will be wondering how did you do in order to earn at home and that's the time you're going to tell them or show to them what's on the list. As easy as that, and don't ever force people to invest in bitcoin let them go to you and ask what they're going to do in order to earn profit.

There's a lot of reason why people chooses/attracts to Bitcoin rather the other cyptocurrency, I will list down all the reasons I know why people chooses Bitcoin rather the Altcoins this is all according to my own opinions, perspective and experience.

1. The stability of Bitcoin.
2. You can easily Earn it through working here in the forum or to other freelance works.
3. Can be used as a mode of payment.
4. The price is High.
5. Most know cryptocurrency in the market and in the industry.
6. The fast change of the value because of volume in exchanges.
7. Most  online stores, shops recognize it as a mode of payment.
8. Can be used as Investment.
9. Can be used as Savings.
10. Can be use in gambling.
11. Form of transaction.

There's many reason why Bitcoin attracts a lot of people rather than the altcoin, but we have different reasons why we choose bitcoin rather than altcoins for me the reason why I choose bitcoin rather than altcoins is because of It's stability even though I will leave it for a year I know in myself that the price of it will not crash instead It's price will increase.

This one is funny. Bitcoin or cryptocurrency can't be a subject in school (I don't know what you're thinking.) It's like teaching "DOLLARS AS A SUBJECT IN SCHOOL" do you think academic institutes will approve that kind of subject? hell no.

You know what? everything about bitcoin and all about cryptocurrency can be found in the internet. All ways on how to earn, different strategies in trading, investments, savings,  strategies in investing to ICO's and even making your own coin can be all found in the internet actually a teen or kid can learn bitcoin/cryptocurrency if they want through internet. My only point is why do you think it's a best way to have bitcoin subject?

There are a lot of strategy in trading cryptocurrencies, the most common strategy is what we called "Buy low, Sell high" I think you already knew that. So you're wondering what coin you should buy? you can check the first 10 or 15 coins here in https://coinmarketcap.com/ and study every coin well and try to invest in it.

If you're looking for detailed strategy i can give you a link. I've read this blog last month ago and i think this is a big help it includes detailed strategy, entry points and exit points etc.
Here's the link: https://www.deepdotweb.com/2017/04/30/tutorial-altcoin-flipping-cryptocurrency-trading-strategies-always-win/

Cryptocurrency trading is very risky you may end up losing all your money, so before you start trading cryptocurrency you should know the risk you're going to face and that is losing your money because in trading there's no guarantee that you're going to earn since the market is unpredictable. So what i can recommend you before start trading cryptocurrency is:

1. Study the basics about trading (reading graph, candle sticks,etc.)
2. Study different strategies in cryptocurrency trading (Google and youtube would be a great help)
3. Study coins that has potential (Do your own research)
4. Apply your learnings, so i would recommend you to use demo trading there's a lot of sites that has a demo feature meaning you can experience trading without investing money.
5. Once your confident enough try to invest small capital to real trading.
6. And once you're familiar in trading you can now start trading cryptocurrency.

So remember that there's a high risk in trading cryptocurrency so you better invest only what you can afford to lose.

Yes, It's a kind of trading strategy wherein you're going to buy a coin that has a low price and you're going to sell it when the price goes up but in order to be successful using this kind of strategy there's a thing that you need to consider first such as:
Coin on where you're going to invest (Study)
Entry points and your exit points

But first before you start trading you should know that there's a high risk anywhere when it comes to investing so there's no guarantee that when you hold long you will earn, so invest only what you can afford to lose. If you're going for a long term investment i would suggest to buy Bitcoin(BTC) and Ethereum(ETH) because it's the most stable coin from the start.

Nope, first thing is that I'm a student and of course no one's gonna lend me money because they think i can't pay them and so i made a goal in my mind which is to earn without buying any bitcoin through fiat or to borrow money to buy bitcoin. I started with a simple signature campaign and earn after i earned profit i divide it into 3 parts

•   Investment to ICO's
•   Investment to trading
•   Savings
And after some time i managed to have some investments and savings and right now i just circulating my profit, from the profit i've earned to investment and from investment to savings and yes it works for me until now. The thing here is that you don't need to borrow money or to buy bitcoin you can just work through forums, freelance site that pays bitcoin and use your profits and knowledge to invest to projects, ICO's and even trading.

There are many good reason why it's good to have some BTC here are some of the list why it's a good reason to own some bitcoin.

1. Like what you've said if you lost your wallet you can access to a online wallet to withdraw some bitcoin (The bad thing here is that bitcoin is not a universal currency some of the countries didn't recognize bitcoin.)
2. Once you have bitcoin and you hold it, soon you will become rich.
3. You can pay others whenever they are and the transaction is very low.
4. Fast transaction.
5. You can have bitcoin whenever you want, wherever you are and whoever you are.

So far here are my ideas why it's a good reason to own some bitcoin.
