all i am saying is that there is no need to be so dramatic about the fall, because it started from $800 and now it is at 870 (or even at your bottom it was still $43 above the price it started from.

it is a correction

obviously it is not even a good idea to talk about bitcoin with kids of low ages such as in elementary! i think when most people here say kids they mean 16+ and that is understandable because they are mostly understanding newer technologies and won't find it strange and can easily understand how bitcoin works compared to a 60 year old

well first of all your IF is a big IF that is not going to happen.

also you are restricting your calculation to only US, you should take into consideration that the whole world is using bitcoin not US so you have to consider all the fiat currencies in the circulation not just USD.

but also at the same time i don't like this comparison because as i said fiat is not going anywhere. and in the end not all people are going to use bitcoin but they are all using fiat.

technically you can not call it paper wallet since that word means a wallet that is printed on paper!
if you are looking for a cold storage, then it is a different story.
as long as you have created the private keys offline and in a air tight computer and encrypted and stored them safely then you can consider it cold storage.

what dump? you people seem to forget what price has been before the so called dump. it was $810ish and now it is $870 dump is if price went from $810 to $600 that is called dump but when (like what happened yesterday) price rises first and comes back down a little it is called correction and over all rise.

if the rise stops at $890-$910 and like always starts struggling around this price i wouldn't expect much news release regarding bitcoin but if you saw a rise bigger than that in a couple of days (max 1 week) from now you are going to see this topic again: "China bans bitcoin" of course like the last 100 times it would be pure FUD.

the investopedia links above are explanatory enough but in my opinion you can say trading is an investment that you need to work on it too. but the opposite is not true.
generally when you invest, you don't do anything apart from hoping that what you invested in becomes successful and gives you money (profit) but when you trade, you invest your money and have to work on making that profit happen.

not from there but in the streets of India apart from rivers of poo, bitcoin price is 66600.0 (~$980 according to xe.com)

the reward halves approximately every 4 years (every 210,000 blocks) already happened twice from 50 to 25 and as you see today to 12.5BTC

the fee amount is not fixed in all blocks, you have to find them one by one (0.69552371 is only for one of the blocks) they are usually about 0.5 to 1.5
so it would be 10 * 12.5 + (fee of 1st block + fee of 2nd block + .... fee of 10th block)

i have never mined so i am not sure about this but how much each individual miners earns when connected to a pool depends on how much share they get based on their hashrate and how much fees the pool is going to take and how they share the earnings.
and the earning of the pool owner is from those fees AFAIK.

who said anything about bitcoin, anything about being public, or showing the source code?

this is my speculation based on what i have read:
it is the technology they are going to use. which means a blockchain that they will use "internally" hidden from eyes of anyone outside. they will have their own internal miners and everything will be centralized and closed source. so there is no blockchain for you and me to see, there is no miner that we can attack 51%
by doing this they can have super fast, and extremely secure way of transactions with zero possibility of any kind of attack in the middle.

and also there are anonymous transactions that can be used even if the blockchain is public. so it can solve the problem of privacy.

i am 100% in bitcoin.
but i use it to trade altcoins, i don't consider what i do as investing in altcoins because it is too short and i don't keep them for long, in other words i dump fast enough to get back in bitcoin.
however i am doing it with a small percentage of my coins, something around 40% which changes from time to time.

why would you want to know, and those who have made big profit are never going to announce it here!
surely there have been many who sold and bought and made profit and loss. that is how any market works. some experienced traders are always silently making their money while the rest of us talking here to ourselves

well you can't and it is a pretty hard thing to do.
what important thing you have to know is that unless the pools are announcing they mined that block or they mine to a known bitcoin address, there is no way of knowing which pool/farm mined which block.

considering that, when you click on the link like this: https://blockchain.info/blocks/BTC.com you see the blocks they (supposedly) have mined, then clicking on each block hash you can see the timestamp of each block, add up the reward+fees and that is how much each of them earned in the time-frame you have in mind.

example: https://blockchain.info/block/0000000000000000032adcc90c8f7b24d12a0ef83d12093b0a21a543d2986551 found by BTC.com
has 2017-01-16 14:19:46 as timestamp
reward: 12.5 + 0.69552371
now go back to timestamp bigger than or equal to 2017-01-15 14:19:46 for last 24 hour

this(https://blockchain.info/address/3NA8hsjfdgVkmmVS9moHmkZsVCoLxUkvvv) seems to be the address they mine to, you can use things like this to add up how much each pool is mining too.

you can also write a quick code to get the raw block information then add up the reward + fee based on the timestamp in the raw block

i just answered this to someone else in another topic:
https://bitcointalk.org/index.php?topic=1294465.msg17522642#msg17522642
there are many countries that have announced bitcoin as a legal currency or commodity and these are only big countries with lots of bitcoin user. the rest are aware of bitcoin and said it is legal but didn't announce it big time since there aren't that many users.

you can also see this:
https://en.wikipedia.org/wiki/Legality_of_bitcoin_by_country

many countries have accepted it as a legal thing. the government have also announced it. for example
- Chinese government has announced that bitcoin is legal and trading it is allowed.
- Japan announced bitcoin as a legal currency and usage of it as currency or for trading is legal.
- US also regulated bitcoin trading and has even issued licence to many businesses.
- Canada done some stuff that i can not remember at the moment.
- Russia is supporting bitcoin and its technology and has allowed trading bitcoin.
- and many more.

i suggest putting all of these in one place, preferably somewhere trusted like google (i think it is called survey) and you can add all the questions in one link and then post it here and on reddit, maybe twitter if you have an account with bitcoin followers.
one good thing about it is that google will draw charts easily for you too.

also it helps make a relationship between these, for example you can see the relationship between Age and Income.

haha, that is true and the main reason for it is because bitcoin price is so volatile. when people think what they have is going to worth a lot more in a while they won't spend. but if price becomes more stable, they will be more willing to spend bitcoin.

and to answer your question i have to say nothing much, mostly digital things. but mainly i want the places already available for those things to start accepting bitcoin not a third party because that really is not spending bitcoin unless it is at a discount and at a trusted place.

i don't quite understand the reason for a market panic either, but generally it is because there are too many weak hands in the market and whenever there is a price change they all start thinking things are over and get scared so they start selling to not lose money and when it starts it can not be stopped until they are flushed out.

you should explain which part is that you are failing at. i can not tell from your comment!

you deposit an amount (a very small amount may not be credited to your balance since many exchanges have some rules about these things, check this out first) then after you saw that in your balance tab you go to the ETH market and fill in the boxes related to buy order.
set the price and total amount to buy (you can click on your balance to automatically have that filled) if 0.0001 is the minimum on polo then you can place an order.

was this clear?

if i was a betting man i would bet on the price to go to $2000 and more in a year or so.

so far we have seen price rise from 0.01 to 1 dollar and that is one 100x rise and then from $1 to $10 which is another 10x rise and then there was the rise from $1 to $20 and then $200 and finally in 2013 we were proven that price can go to $1000+ and that is 10000x rise overall.
in other words nothing is saying a teeny tiny 2x rise from 1000 to 2000 can not happen.
