A relatively good way may be signature campaign, for people who are starting their new journey into btc world, because it can helps them a lot to earn btc without complications. I also suggest to sell service to other members like offering your programming skills or web designing and get paid on bitcoins.

Probably only in case we lost internet connection, and all over the world , then i would say yes, btc and all other online payment forms would disappear, but that is very unlikely to happen...

If you can not control yourself, I think you should ask your family to help you to manage your money, watch you and stop you going to gambling . The you will find no way or lose interest to gamble.

I believe that without signature campaign you probably could earn through the freelance work or offering goods and services, check the services section.

Bitcoin is becoming more popular everyday. More people are getting to now what Bitcoin is. I would say that, as a result of this, Bitcoin is becoming a global currency.

I would consider selling things that I don't need, or that are not very important for me in my daily life. Then I would use part of the earned money to invest in something with potential to give me profit.

Really difficult to double bitcoins. The best way to double the bitcoins is by playing trading. Trading can make us get a great advantage when choosing the right time to sell and buy the coin.

I use them for both, currency or investment. Because I make profit with bitcoin trading and I also buy sometimes stuff with it, mostly digital stuff. And I save good part of it for the long run.

There are multiple possible methods, I myself use signature campaigns to gain some profit, with my other bitcoins I really do nothing else than holding. I think holding right now is one of the best things you can do because of the fact that the bitcoin is gonna rise to a higher amount.

Yes, in my opinion the bitcoin is very safe, the bitcoin has a very good future and its one of the safest pay methods available. I even think it's more secure than a bank in my opinion.

At this time, no I would not. Bitcoin is so volatile right now, the risks outweigh the positives. Yes, I could make thirty percent profit in fiat in a day, but I could also lose the same.

I do not have all of my money in bitcoins but only some amount of my money is in bitcoin, and some amount of my money is in altcoins, while some amount of my money is invested in a project of me, I hope I will earn from all of them.

I think that you should save your money, cutting your spendings by only buying what you need. I think that's a better way to manage your money.

It's complicated to earn steady income from bitcoins as price fluctuations will never help you in reaching there, to make it really steady.

In my opinion, trading is not an very easy way to earn money, like what some people think. There are many good traders who lost a lot of money in trading, even those with lots of experience.

It is not a very simple question... It depends on what the price is at the time.
If I got available money and I find the price not very expensive, I think about buying it.

I do not spend it actively, to be honest. I think that spending the coins now is just not very smart, due to the fact that bitcoin has a lot more to offer in the near future.

I think holding bitcoins could be a potential way to get rich only if the bitcoins price reaches very high level, otherwise you may earn some good profit, but I don't think this will make you rich.

A lot of things, like the decentralization of the system, the simple way to send, to receive money and the low fees.

It depends on your skills and risks that you're willing to take. I recommend BTC/USD trading to minimize risks, but it can give lower profits compared to altcoin profits. Altcoin trading can give you higher profits, but higher risks. It's good to stay away from cloud mining and gambling.
Remember, a lot of research and patience is essential in the crypto space.
