For me there is no impossible, all the impossible will be possible even Bitcoin is, it will last long until more than one hundred years and more people will spread the news and knowledge to support this kind of currency. The people who will get that knowledge will realized that its so helpful to them they will live a life with a purpose and do something great with the use Bitcoin. If I will be a parent in the near future I will pass it to my sons and daughters which they will inherit my knowledge to know the crypto world and crypto market, because into myself that it will helps them  like it did to me.

You didn't include Mining. Making mining rigs with a lot of GPU are one of the best to earn bitcoins, but for me if you want to get it free, go find some bounty campaigns that are paying with btc and try some services that are paying bitcoin like graphics design or translating. Very many services. Just keep searching.

Don't panic in making decisions, rest assured with the future of bitcoin. Bitcoin has a promising prospect in this year, I'm sure that the tough test that's happening now goes by and we'll get a fantastic price, hold bitcoin is more profitable than selling.

make some research in google mate "what is bitcoin" ,and don't ask here if its ponzi schemes, etc.  Cuase that is the stupid question I've ever seen here in forum. how bitcoin become a ponzi cause it is a decentralized digital currency and its working without administrator.do some research mate don't rely on other opinions.

Media do not againts bitcoins. Media doing news from situation or someone pay for news, and media doing news how that person want

Will another coin beat bitcoin in terms of total market cap? Maybe, maybe not. Is it possible? Very possible. Though Ethereum is slowly but surely closing up on market cap(currently a 57.3 billion difference[1]), it still has a far far way to go; and I honestly don't see bitcoin being replaced soon. Probably in the future, but who knows? Too early to tell. And it might not even be ETH.

I do not think the global regulation of bitcoin will kill bitcoin, it will be more reinforcing and more reliable, global regulation of bitcoin, is what the world is waiting for, to make bitcoin into a hot currency, and universally acceptable. See something that has a market market capitalization of more than 800B USD is considered to have involved many people from the market.You can not say it govt.Can leave a very popular thing like it is not regulated. Rule will come. Only if bitcoin can curb its way out of such norms will it only be said to be global currency or environment but yes it will have a very negative effect.

I've learned to stay away from Revenue Sharing Websites as they are all just Ponzi schemes waiting to run away with your money once they think they will have enough to hide from the face of the earth.. People, stay away from revenue sharing websites.

I try to increase my portofolio with alts. I don't have the cash at the moment but with wath i can spars i try to buy btc

What an incredible year 2017 was for cryptocurrencies. Having begun the year with a combined market cap of less than $18 billion, the aggregate value of all virtual currencies by year's end hit $613 billion, representing a better than 3,300% increase.
Cryptocurrencies soared even more to begin 2018, hitting an all-time aggregate market cap high of $836 billion on Jan. 5, before losing a little bit of steam.
These are essentially lifetime gains for investors that have been crammed into a span of just 52 to 53 weeks!
Yet, what's really interesting is that bitcoin, the world's most valuable and popular cryptocurrency, wasn't a primary focus in 2017. Rather than investors flocking to bitcoin, the goal among digital currency investors became to find the next bitcoin.
As a result, a number of burgeoning cryptocurrencies ran circles around bitcoin last year.
In particular, Ethereum, Ripp, Litecoin, and Dash were veritably unstoppable, with respective gains of 9,383%, 36,564%, 5,260%, and 9,282%!
