Yes, bitcoin does  have a fluctuating value. The price is not constant. Think about the demand-supply curve. The amount of bitcoins circulating is limited. So if more investors starts to invest on bitcoin, the price starts to rise slowly. But if investors starts to sell off their investments, the price starts to fall again, hence causing the fluctuation in value.

Ripple/XRP received too much attention last few weeks causing the price to skyrocket to around $3 per coin. The price started to go up after rumors were spread that coinbase will be adding ripple/xrp for exchanging. But this hasn't happen and after recent announcement made by coinbase the price started to decline once again.

If bitcoin dies completely we can almost be certain about the faith of the rest of crypto currency. If bitcoin fails to live, other crypto currency will follow and die the same way. This is just when bitcoin becomes totally valueless. But if the faith on crypto currency remains strong, even if the value of bitcoin may falls, other currency which offer better functions might have higher value and still live.

The articles aren't very recent and has been circulating around the internet for last 2 months. They advised users to get out of bitcoin as it will crash soon, but bitcoin still exists with a very strong value. It is really stupid to compare bitcoin so called "bubble" with dutch tulip mania incident. Tulips had no financial value which could be used as a form of payment, but bitcoin does have it.

Actually impossible for the price of bitcoin to reach around 1 million USD within the next few years. We may have to wait for a decade or more. The max we can see the price reaching within the end of this year, that is 2018 is around $40,000 USD, if we do not face any kind of absurd obstacles.

If ripple becomes the top currency then it will just surpass the market cap of bitcoin. Nothing much. Its not like it will destroy other crypto currency. Its not possible by ripple alone. And bitcoin will also rise in value before this even happens. The price has been around 14k-15k  USD for a while.

All I see right now is the government being more involved in blockchain technology by trying to regulate it and bring it completely under their control. The technology but will still be used, though it won't be decentralized anymore. This centralization will have its both pros and cons.

Right now you can invest on Ripple and Stellar. They are receiving enough attention causing the price to go higher. You are still not late as we can expect the price to go even more higher anytime soon. ADA and ICON are also some coins you might consider investing on.

Ripple/XRP has already received a lot of attention recently. This has already caused the price to skyrocket and has crossed $3.5 already making it the second most valuable digital asset.  Once it hits the mainstream market completely we can expect the price to go even much higher.

That's a great list. I have already invested on few coins you mentioned before the bloom took place. Not disappointed at all. Stellar Lumen (XLM) has given me the most profit as of now. Ripple/XRP has received enough attention in last few weeks and the price has now already gone above $3. ICON (ICX) also has a good chance of bumping up high.

The price went up within few days last year. The sudden growth was abnormal as usual since the cryptocurrencies don't follow the general economic law. This correction was much needed. Right now we are seeing the price being stable and fluctuating around 13500USD to 15500 USD. Expecting to see a new all time high!

There are lot of third party sites offering bitcoin debit cards both in plastic form or virtual. You can try spectrocoins debit card which you can used on any ATM across the world. You can also try ADVcash. They accept bitcoin to deposit money.

Besides choosing BTC and ETH, I would go for other top crypto currency. Will use those coins for storage value and to make long term profit. There are litecoin and Dash coin for using them as storage value. To make quick profit right now, I would go for Ripple.

If the user does not have access to the dead owners wallet/private keys, then yes! By yes, I mean that the coins won't be lost but can never be accessed. It will still exist in the supply but can never be used. There are supply cap of bitcoin, and it will remain constant. The coins which can not be accessed will not be replaced by new bitcoins.

I usually spread my investment on different coins first. This helps me to cover up losses i would have made of other coins fell in price after i invested. I then keep a profit gain threshold level. Once the level is reached I sell my coins and cash out my profit. If the price falls i just hold them and wait for them to recover.

The price has fell down a lot from $19,000 USD to $11,000 USD. It is now fluctuating around $13,500 USD  to $15,000 USD and has been stable here for a while. So I guess now is the perfect time to buy or invest on bitcoin. Once the wall break we will see a new all time high!

The best thing to do is to buy bitcoin with your credit card. Transfer those bitcoins you bought to an exchange. Now exchange your bitcoin for the alt coins you want. This is somewhat safer than buying from random people you come across the internet. Around 80% of those will just try to scam you.

I used to keep track of forks, but with the current conditions we can see tons of shitty forks going on. All of them are so shit that they shouldn't even exist in the first place. It has become a total joke starting from bitcoin gold.
This isn't the real segwit2x which was supposed to take place but got suspended. Some shaddy new developer using this name for their own advantage!

You should keep bitcoin as your first priority of investment. Would suggest to invest at least half of your investments on bitcoin.
For alt coins you can try investing on top crypto currency markets. Try ripple/XRP for now. They have been receiving a lot of hype recently.

The price has already fell and is right now more stable at $14,000 to $15,000 USD for more than a week. We can expect a new all time high anytime soon. This rise happens every time the price falls and is stable for a while.
When the fee increases people will be using bitcoin as a storage value.
