With millions in number of nodes, there is no doubt bitcoin is safe. It is only the fault of a user that its wallet is not secured enough or wrong sending of Bitcoin by mistake should there be a problem.

In my opinion BTC will and can never lose it popularity. Most novicees and uninitiated introduction to cryptocurrencies starts from bitcoins, before they even learn about other coins. Yes it can lose it value in the market but not its popularity.

We use ethereum wallet because we can generate tons of addresses for you to use if you don't want to be tracked when buying or receiving coins. The encryption is okay too, which is nice.

Trading works fine, you just need to take time reading and studying the basics of trading after you will start. I think you need to take note of why you lost these amount and learn from it and you'll never have the same experience again.

At first you can just keep your Bitcoin. Or you can try leave 70% in the Bitcoin, 30% keep the aitcoins. Do not focus on one type of investment. Create at least four or more types of investments.

You should find some promising ICO's at first and buy their tokens. If the project is worthwhile, you will easily get x10-x30 profit to your deposit. Of course it is a bit risky, but the future profit can be huge. Or you can choose simple way - invest to etherium or bcash.

I don't think ICO's will die in 2018 because there are many people who create new coins and technologies. Without investors altcoin and BTC markets will die, so we need investments and different places to invest so capital can flow to and from the cryptocurrency market.

It will be interesting to see how the price changes for a 5 years. But I think BTC will be always good in its development. I am sure in the next 5 years, BTC world will always grow.

It would befogged BTC holders, so there will be a big tendency that they will lose faith in cryptocurrency. If the BTC died or falls down then loss, it will be a slaughter! Yeah specially to us who invest in Bitcoin.

I believe if we have a good source of money and knowledge to get involve in BTC investments, so it wont be a problem if we quit our job to make invesments, but investing can be very dangerous you can lost money.

Bitcoin will be worth so much more in the years to come; if you can afford to invest, this is absolutely the best thing to invest in.

Daytrading is more fun than just HODLing. You will get more knowledge about cryptoworld when you trading, but you get nothing when you hodling.

I usually spend my money from bitcoins to daily needs of my family. although it is small but for us we value the money that came from bitcoin.

I don't see any reason why not as we can see that bitcoin is the most promising investment of all time this year. As I what I have researched, billionaires have already invested in bitcoin in previous years which cause to become richer as they are currently holding it.

Is it true that only the main developer can code for the coin and improve it? I'm sure at some point in the future, applications will be built on top of it.

Everything has a risk as well as in this business that we have. There are ways for you to ensure that the ICO is safe, all you need to do is read every single details of that project - you need to consider the team who manages it.

Social media like Twitter,telegram, facebook, medium,slac and youtube. If you search carefully you can get lots and lots of information about any coin and also all news about particular coin.Also you can subscribe some youtube channels,telegram channels,facebook groups from that any news you can get easily.

You can invest some but don't assume that it will most probably increase its price to that amount.

It's Bitcoin and Etherium. And this is absolutely. Significant growth of bitcoin, so the trend will continue in 2018.

Crypto is going mainstream and this is just the beginning of huge movements. Extremely interesting stuff to come and dive right in to. First we had simple cryptocurrency for exchange of value and now is the time of decentralized communities, marketplaces & more.
