Bitcoin is decentralized and is not under the government that's why it has no tax.

Tax in transaction? Do you mean the miners fee? The miners fee goes to the miner who mines the block with your transaction but don't worry miners fee is much cheaper than the fees we have here (Banks, remittance centers etc.)

HYIP, Cloud mining and gambling are the things that as much as possible you should get away with. Why? Because it doesn't guarantee profits.

Trading,  freelancing and joining in a signature campaign are the ones that are profitable. As long as the exvhanger/employer/campaign manager is legit.

Yes. It will serve as a improvement material and can give birth to game changers

However,  Us investors/potential investors are having a hard time choosing the right ICO if many of the same kind released at once.

I already added this to my watch list and will see how it goes. This one is perfect for privacy freak like me.

The best way is to try freelancing jobs but it depends on what skill you have/What you can do.
Here are some sites you can try, They pay bitcoin.

1. https://www.xbtfreelancer.com
2). /r/Jobs4bitcoin  (Reddit)
3). https://coinality.com

Or you can try on upwork or fiverr.  They also have simple jobs.

Some advice, Your two hours a day is not enough to make a 1 bitcoin in just 2-3 months.

It is much better to just focus on your job than freelancing on some sites.  Because you can just buy some bitcoins using your salary and keep it for investment.

Gambling is so addicting because we all love the quick money things but unfortunately most of them are scams. 

One of the proven legit quick money stuffs is Gambling. You have a chance to earn lots of money, Just by playing.

But the chances of making huge money from gambling are actually lower because the house is the one who mostly wins.

Luck is just one of the factor that can affect the outcome of a game.  If you're not lucky, it doesn't mean that the outcome of the game is already decided.

You can still use some tricks and you can also analyze the game.

But if you're talking about dice then I will agree that it is based on luck

If its poker,  You can't just depend on your luck because you will certainly lose if you did.

Global currency is a currency that is accepted for most transaction especially international transactions.  And I think as of now its either USD or Euro.

Bitcoin is an alternative payment system and I think it is designed for all transaction to the point that most people call it  "One Currency For All"

However, As of now there are a very limited number of merchants who accepts bitcoin but it is definitely increasing so if bitcoin will become widely used all around the world then it can be.

Of course because there is no absolute freedom. Rules and regulation are everywhere and there are consequences if you break it.

That being said, There is also no absolute freedom in bitcoin .

People thinl there is because bitcoin has a loose rules and regulation compared to the tradional payment system and is much easy/comfortable to use.

It is not right to teach bitcoin to kids because they are too young to handle money and they are more interested in playing. Being a kid is fun but its short so let them enjoy their childhood.

I am also agreeing to others that we should teach bitcoin to teens instead. Because I am one of the teens that got interested in bitcoin tho there is only one year left before I reach the the legal age.

There are lots of good articles all over the net that's why I haven't read any books however I listed some titles that you guys recommend for future reference. 

My other source of knowledge about trading are:

1. Trading discussion on forums (bitcointalk, reddit etc.)
2. Youtube Vids
3. Experience

Agree.  Because keeping a large amount of bitcoin in an online wallet is risky. They are always a target of hackers.

As much as possible when storing a huge amount  of bitcoin, Keep it in a cold storage.

It is less risky if you have a full control of your wallet. So look for the ones who gives a private key.

It happens when I told to my friend that I need some extra income then he introduced me to bitcoin, Teach me some basic stuffs and his source of income.

At first I didn't believe it.  I thought that my friend was trying to lead me into some pyramid scam (AWWWW) but fortunately it's not because he showed some proofs.

And them I started doing some things that he does also for bitcoin like being active here.

I think that bitcoin itself is the most profitable and less risky investment you can have. It is already proven that bitcoins price increases a huge amount every year.

If you're looking for investment aside from bitcoin itself you can Invest in
Altcoins or Gambling site.  Just take your time in choosing the right coin or gambling site however, You must not forget that this is much risky than keeping bitcoin.

No it won't be worthless because bitcoin is just an alternative payment system no matter how its price rises. It won't take over paper money unless we enter an age where cryptocurrencies are the main money we used.

Yes, The merchants that accept bitcoin is very limited but I can stil use my bitcoins by converting it to my local currency, The negative part of this is I have to pay 2 different kind of fees.  One is fee for the exchange site and One for the remittance center where I will get the money.

I can only spend my bitcoins directly to online shops like purse.io.  It will be nice if bitcoin is widely accepted so we can have low fees when spending them

If you send a bitcoin to someone, It will show up in the wallet in seconds but the confirmation time can take 30-40 minutes or even an hour.

It will be hard for local stores to accept bitcoin as you can cancel an unconfirmed transaction.

The only way to speed up the confirmation time is to pay a higher miner fee because the miners typically pick a transaction with a high fee.

It's one of my productive hobby cause it allows me to earn extra money.  If you're asking how serious I am in bitcoin, I guess I am one of those who takes bitcoin seriously because I believe in its potentials that can exceed my expectations in the future.  

I have a lot of hobbies but I guess I spend most of my time in bitcoin. And it has helped me a lot in my financial problems. 
Enough reason to be serious about it.

As of now bitcoin can't really help me in my daily needs because it is not accepted anywhere here in my country. I only used it in online shopping and reloading my phone.  However it allows me to earn money that I convert to my local currency so it definitely helps me in some ways.

But my main use of my bitcoins is investment so its fine if no merchants here accepts it.

Yes, We should spread awareness about this because the risk of keeping all your coins in an exchange sites is high. Why? Because exchange sites are a common target of hackers and even online wallets. OR sometimes exchange sites can ran away with your coins.

Our money is important that's why we should store it in a safe place. I suggest that you should store it in any wallet that has a private key, to make sure that it is yours alone.

I honestly don't recommend online wallets srsly

I doubt that five years is enough for it to be used by everyone.  That future is vey likely to happen but its still far from now.  Well it is safe to think that after all bitcoins are mined then I think almost everyone are aware of bitcoin already.

Bitcoin is still new and developing you can't expect such good thing to happen right away.
