yes, some of it not all. i have already converted most of it back to bitcoin when it was pumped. i am holding some more because i missed the chance to sell it on top so i am taking the risk of holding it until it is pumped.

use? there is no way i can "use" them. the only place that i can send them to is an exchange where i can sell these coins!

usually when people invest their bitcoins they are looking for making profit on bitcoin. so if an altcoin stays the same price in BTC for the time they have invested in them, they are losing as an investor because their money (bitcoin) is sitting idle by without any profit.

as an altcoin trader, you usually don't care about bitcoin fluctuations in short term. you earn more bitcoin (profit) and in long term that profit is also gaining profit in USD since bitcoin rises in long term.

they are not really creating new "cryptocurrencies". they are creating tokens that can be traded for a little while. and it is all about the money. it is pretty easy to create a new altcoin, you just have to know some basics of programming and some experience of what to change. then you can simply take some code (all are open source) and make your own altcoin. add it to a pool and an exchange, advertise and profit.

although it sounds easy, it is not profitable as you may think. because shitcoins these days are not capable of gaining much value.

nothing about it is ready yet
you need to wait until it is really released and then you will surely find links on their website which is called BTCGPU.org!
the release date is October 25 by the way.

fiat is already half "digital", it doesn't have to be the far future. soon it will be 100% digital and most probably a big part of it will involve blockchain technology because of the way banks are currently working on it with so much interest.

but things like bitcoin (a decentralized cryptocurrency) will always remain as secondary option in my opinion. it can not "replace" fiat.

it will always depend on the country you live it.
some of them may not even tax exchanges and some may not even have any exchanges in their country!
however this is a market something similar to Forex market and eventually if it becomes big and much more popular, surely the government will start looking into ways of taxing it.

these questions really have obvious answers!
just take a look at the charts and how price moves. put yourself in those times when price is rising or falling and try to think what will you feel if you had all your money in bitcoin and price went up 20% or went down 20% in a couple of days.
i think that will answer all your questions.

first of all you can not really call this a "dump". this is just a small drop in price. a real dump (which is going to come at some point by the way) will be at least 20% big. this was a couple of percentages!

secondly what did you expect? you can't pump an altcoin for eternity. at some point the price stops going up and reverses until it reaches some equilibrium. then it can go up or down from there. although as i said it is not yet dumping.

LOL, 1-2 years is a very long time to stay alive. most altcoins don't even last a couple of months before they get dumped hard, and then their blockchain dies and eventually they disappear.
i'd say if it stays around for 1-2 years, it will be doing fine.

despite what you said i have a different speculation about BTG, i believe that because it is GPU mineable and also because the fact that it nearly coincides with the death of ETH mining, there will be a decent support for it which can keep the coin going.

technically speaking smart contracts can be an additional feature which opens up a lot of opportunity for creating new and interesting things. i believe there was a good article on bitcoin wiki about smart contracts.

so that can be a lot more usage and that creates a lot more demand. but the issue is that as long as that usage is really useful not some temporary fake hype, the demand will last and in long term helps more adoption and increase of price.

for things like ETH, smart contracts start and end with ICOs in my opinion and so far i have not really seen anything which is really making something useful.

litecoin price has been stable compared to many other altcoins and it has a lot of potential to rise and actually there is a good chance to have a big pump in near future.

in any case if you feel uneasy holding LTC then sell it, remember that it is always better to have your mind at ease rather than invest and have the stress of holding something.

but you don't have to sell all of it. you can sell some until you reach a level that you are more comfortable with.

this is one of the reasons why i like Litecoin.
i see the developers being actively involved with the coin, and obviously they also have invested in it. and when you have your money invested in something you will do everything in your power to improve that thing.

most people just look at the social media and jump in whatever is hot and whatever others are telling them to buy. that is why most of them lose most of the time!

i am no expert but what i look for is fist the chart, to see how that coin is doing. sometimes there are deal breakers for me like if the coin was recently pumped and if i see the price in a bubble.
if i don't, then it is a good investment chance. then i look for the hype. that is the social media to see if it has anything coming to it in the future which can indicate a pump.

of course there is a riskier way that i have been messing around with and that is watching the market every second and as soon as you see a rise, you jump in and enjoy the ride.

what fees? trading fees or withdrawal fees?

their withdrawal fee is medium, i wouldn't call it high nor low.

the trading fee is high though. it is a small amount 0.25% versus others being 0.2% or 0.15% but that small amount can amass to a much bigger sum when you trade a lot and trade larger amounts. but that is the price you pay for using an exchange which is better than poloniex.

this is not really a good way of "getting" coins though.
first of all freebitco.in claims to be mining Monero which is something you can mine with your CPU, secondly i have to say something that you mine inside your browser can not really be efficient. you need to run a miner, some code that is dedicated for mining only not some script inside your browser.

ETH is a bubbly mess with a scary hard fork coming on.
Dash is a premine pumped coin but still better than ETH
Doge is a joke created a long time ago and with the worst supply and distribution of all altcoins.

Monero and litecoin are only coins that i can agree with. they both are good and with some good potential.

you have 0 proof of that and you are just making a big guess based on nothing.

even the Chinese trading volume is barely 10-20% of the total trading volume

and you think ICO and bitcoin are related!!!!

now you just contradicted yourself!
if China really had the effect that you claim they have with your claim of them holding 50% of bitcoin, price should have continued to drop not recover!

it is all good though.
each time there is something like that and they create a new altcoin forked from bitcoin, it just makes bitcoin stronger.
of course the first time there will be a lot of panic because it is unknown territory. but after a while it will become old news. this upcoming one is the second one after cash and it will have smaller effect. and after that i don't think there can be any other fork that is capable of creating any fear at all.

NEO is practically ETH without the huge Ether foundation behind it. all the rise you see is because of that but you can not expect unrealistic rises to huge prices because NEO lacks the support of the deep manipulative pockets that ETH has.
and that is a key difference which can make the coin go as high as $300-$400 or never go above $50-$100

if you mean addresses belonging to one coin and in one wallet then usually the coins i have seen are deterministic meaning you only keep a master key so you can recover all of them with that.

if you mean multiple coins each having addresses then again you just have to keep those keys. or the wallet itself holds it and back up that wallet. but most people keep their altcoins on exchanges anyways so they just hold an account (user name and password!).

besides you don't really need to keep track of them. you should always only have 1 address and not reuse them. specially with altcoins which you just hold until you sell there is no need for multiple ones.
