Bitcoin has very good developer support, and i don't think there would be any kind of problem that would cause bitcoin to die. Even though if there are such problems, fixes and solution will be found and put forward soon. Even though the fee might become an issue, bitcoin still might not die since people will still use it as a store value.

The best way to make profit is to keep your self updated with current news and affairs going on within the crypto world. They are strongly related to market and the price. If someone well known or a famous site talks about a coins, we can see some significant rise of the price. Also spread your investment to few different coins. This was you are able to minimize your risks.

You can earn bitcoin the same way you earn fiat. Just instead of accept fiat, accept your payments in bitcoin. Or you can use your fiat money you earn to buy bitcoin and store them. Bitcoin is a form of currency, and no one will be willing to give away free money.
Or you can join campaigns and giveaways to get some coins and get started. But it won't be enough to cover your daily bills. Just some few dollars to spend on beers  
My current signature campaign pays me around 0.025btc/week.

You just have to follow the classic rule. Buy during dip, sell when the price is at the peak or you reached your profit threshold level. You just have to predict when the price is going to floor and when it is going to reach the ceiling. But just do keep it in mind that bitcoin price tends to move upwards, so if you invest anytime and hold it for a while, you have a good chance of making profit.

Its never too late to buy bitcoin. You are now regretting that you didn't buy any when the price was below 3.7k USD. The same way you will end up regretting if you don't buy now, that is during the current price ~ $4.1k USD. We are expecting the price to go over $5000 before 2018.

There are legit ICOs and again there are scams. You will just need to remove the bad ones from the good ones. You will need to use your own knowledge. Just reading the white paper does not mean you will be able to judge which one is legit and which one is scam. You will need to see their team. Most of the legit ICOs have well known developers. They will also have a working platform and keeps users up to date all times.

They use social media platform to start their advertisements. They offer bounty to users who starts to advertise on their behalf. Through those advertisements they show what they have to offer. They use top class and well known developers to develop their ideas. They also offer bonus tokens to early bird investors. But most people starts investing on ICOs to make some quick profit. They assume that after their release of tokens in market will give them some ROI with profits.

You can't just compare bitcoin with ethereum or ethereum with bitcoin. They are two whole different crypto besides having monetary value. They are both different projects with different aim/plan. Bitcoin is a plain stable digital currency where as Ethereum is used as a smart contract application.

Out of those 1130, most of them are just shit. They are made for just pumping and dumping for making quick profits and exiting. Once they exit the coins die. But coins there are developed for real purpose will survive and will stay and be used along side bitcoins without any conflict.

How could you be saying that ICOs are safe heaven for investing money? Whole new lot of risks when investing on ICOs. Lots of shitty and scammy ICOs are out there where once the ICO is over they halt their development. They are  just dump and pump schemes.
Most ICOs lists countries which will be able to participate, so you can easily find out which countries allows ICO and which don't.

Even if everyone starts using bitcoin, in order to impose income tax they will have to regulate bitcoin which then causes bitcoin to loose its key feature - decentralization. The government will also find it difficult to track each and every users, so they will have to find alternative ways to get around and cover/replace income tax with something more suitable.

Don't think math can help you win on any traditional casino. The casino makes sure that you are not able to use any tricks such as counting cards and take any kind of advantage.
I guess he just used the probability to win the lottery. If he some how knew how many tickets each user had you will be able to calculate your win percentage based on number of tickets you have.

It's not impossible but won't be happening anytime soon. You should be considering the market cap and demand when expecting such value of bitcoin. And do keep in mind that bitcoin is still in its infant stage.

Investing on bitcoin might be considered as a form of gambling because it has risks. But the risk can be controlled and minimized to a very small level if one understands the how the market works and keeps himseld updated to current events that's taking place in crypto world.

Spreading your investment would be the best. The more you spread the better it is since you will be facing less risk. I would invest around 60% of my money on bitcoins and rest on different alt coins. But do keep that in mind, if bitcoin does well other alt coins tends to do well and but if bitcoin price falls, the other coins also follows the trend.

You need to get familiar to the words pump and dump. Pump and dumping basically caused change in supply and demand. Pump means the stage of keeping on buying, where dumping means the stage of "dumping" that is selling your coins. Pump decreases supply and dumping increases supply which caused the price to rise and fall. Investors dump when you want to exit with their profit. The price falls down, and new investors come and starts pumping the price.

It's going to be really hard to earn bitcoin without job. Bitcoin is a form of money. People don't give out money for free. You need to earn them. And you earn them by working and working means "job". Collecting from free source will just give you few cents which is not worth collecting.

It's based on the basic - Supply vs Demand  market. The less the supply the more is the demand thus the higher is the price and vise versa, more the supply but less demand caused the price to drop. Various external factors causes this supply demand. For example good news = more demand for bitcoin causes higher price. Bad news (recent china ban on exchange) causes less demand which decreases the price.

I would give them some basic knowledge about what bitcon is and how it works. Won't go too deep though, as they might loose interest thinking its a complex technology.

Depends. But most of the times I trade Btc for alt coins and try making some quick profits. And sometimes it is more easier to buy alt coins using btc.
