Will these are some valid reasons you have mentioned here. but these are not only ways to earn money on the web. and Trading is not so risky if you have enough trading knowledge, cloudmining is unreliable but actual mining is very profitable but it needs good capital to start.
but there are lots of more ways to earn bitcoin.

1: Offering your skills and service.
2: Work as a freelancers,
3: work as a web, graphic designer,
4: signature campaigns (earning of this method may low but it is really worth)
5: bloging and creating website, creating faucets and gambling site also a good way.

Well, thats pretty fair. I think if a company start giving salary in bitcoin thay will also do like this only if their work are fiat bases. like if the campany is usually  a fiat company but just paying salary in bitcoin then this method would be good.

but if the company would be 100% bitcoin related. just like a mining company. then you can't negotiate and have to receive your fixed bitcoin salary.
Receiving salary in bitcoin is just great to be true.

This price increase won't be stable IF you ask me. I think it will drop again to 680 or near it. and you can buy bitcoin that time. and don't sell your bitcoin too fast. you should wait till halving. we are hoping for big achievement in this halving. bitcoin will hopefully touch 2k$ at this halving..
and You are right. almost 75% users voted that they are holding for price increase, and now every holders would be happy after seeing new price.

If it happens, which is pretty much impossible. the we can't do anything really. we can't even sell our bitcoin for low price which we bought for 200$ to 400$ each.
there will be only option for us to hold our bitcoin for more time and wait for again it's price increase.
but it is just a thought. there is no reality on it . how an altcoin can dump bitcoin?

First thing. I am already using some altcoins. and bitcoin too, using another cryptocurrency doesn't mean that you should left bitcoin.. and if I jump to another coin it really doesn't effect bitcoin and its price.
second if by chance bitcoin price fall to the bottom I will also not touch my btc on my wallet and let them there for another price increase.

Finally I got a positive review about [banned mixer]. I am working for [banned mixer] but didn't used it my self. I always felt afraid that what will happend if it turn to scam. if it turn to scam we all will be blame for promoting it. but now after reading @SuperCrypt post. I feel release my self.
I hope [banned mixer] will remain its legitimacy forever and always provide great service as well.

I am 100% sure This is just another Scam Site. like all referral sites, recently I found a site which was giving 10$ per referral, but when I reach payout limit, the link of cashout was still lock. 0.25 btc is too much for only 5 referrals. this is prove that it is an obvious ponzi site.
Remember my words.

HaoBTC website is not working at my end. I don't really like cloudmining sites, I got so much scammed from them and very afraid to invest in another cloudmining sites. but after reading all above posts and users review I though having a look at the site is not a bad Idea. but now I found that site is probably dead.
@OP! will you please see and clarify what is the Issue?

Let Me In too Please.

But watching porn is not the right solution of this problem... getting involved in another bad activity for leaving a bad activity is not a good idea..
if you mean that with focusing on other activities we can be safe from gambling then there are lots of creative and healthy activities that we can do. we should get a right hobby not a wrong thing.. playing games and spending time with parents and relatives can help you to stay away from gambling..

Lots of bad people doesn't care about laws and they don't do what is right. but it doesn't mean that we should leave them and allow them what they are doing. this is like we are also indirectly supporting guns supply and terrorism.
Controlling guns nowadays is not easy but we can still control if if we all become one unit. unity gives strength.
Teach your child about this thing, we should start this mission from our home, lack of education and jobs is the biggest reason of this shit.

You can double your bitcoin with trading. trading is very profitable and also save enough for a experience trader. but it is not that easy as you are thinking. doubling bitcoin with trading needs lots of work and time. and of course trading knowledge and experience are indeed.
first one or two month you may get nothing and some time you may lose also, but don't loose hope and stay with trading and do what you are doing. one day you'll get all rewards of your time, handworks and investments.

Gambling is wrong if you play a lot and lose your all money. and when you got addicted to gambling then it would be more worst for you. you can't left playing gambling and loose more and more, thats why people consider gambling is a wrong thing. try to spend your time in something creative and haelthy activity, gambling really won't make you millionare.

There are almost 80% sites are scam but it is not bitcoins fault, it is fault of peoples who using bitcoin for scamming others..
we have to believe bitcoin, and we have to find legit and genuine paying sites, one suggestion for you don't invest money to anywhere just work on free sources. legit sites don't ask for investment.

There are lots of experience Signature designers working there. I suggest you to Hire Neotox or SFR10. these are very trusted and talented designers.
and also have lots of experience in BBCode designing.
Or you can start a signature designing contest, everyone will submit their entries their selves.

I would not get involved in gambling no matter if I am not rich.. I don't think gambling is only for poor peoples, rich peoples do more gambling then poor. I am not rich but if I were rich I still not gamble, because I don't like gambling at all, and I feel this is just waste of time and lost of money.

bitcoin would not replace the real money, but it can replace all digital currency and payment sources. like paypal, payza, pm and other payment sources, I am sure one day bitcoin will surely replace these systems and become the only one digital currency on the web. I can predict that just because of seeing current usage of bitcoins. bitcoin reached to a milestone only in 8 years. then what will happen next 8 years, can some one imagine that?

But if you ask me I would say that making a plan and thinking about future is must, everyone should have a plan for his future, not a plan to get rich and billionaire but at lease we should safe some money for future if by chance we lose our job, then what will we do? we should think about everything.

Well, the answer is simple, we will save our money in Bitcoin if all banks disappear because of bitcoin.
I also think it can be happen, but I wish that one day bitcoin replace banks. I think banks are not that secure that bitcoins are secure and safe,. there are some issues with online wallets, but if we find a safe place to store our bitcoins then our money will be safer then any bank account.

participating on a campaign is not bad, and it is also one of the most favorite way to earn bitcoin. but getting a whole bitcoin with this method? you may get a whole bitcoin but it will take 6 to 7 month. your current signature paying you 0.035 per week and 0.14 per month, now you can calculate how many months you have to work to get a whole bitcoin. but good thing is it is a free job.
