you are not wrong, the 50% promotion is still running. it started on 20 April and it is planned to run at least until 20 May (about 20 more days remaining)

just write something yourself if you can. that would be so much better and not to mention unique.
all these exchanges have an API and with a simple small call you can take their daily ticker data and use the volume, price or whatever you want and list it in a little widget on your sidebar.

i know some of third party services for "price" such as coindesk widget but never saw for "volume". although again some of these sites like coinmarketcap have an API you can call and get the data yourself.

price is not in a bubble just because it goes up! more specifically when it goes up to where it is supposed to be at. price should have reached $1300 2 months ago before the BUllshit FUD started

it depends on what you are planning to do!
all these "average" sites will give you an average price, just to know what price currently is, i think that will suffice. but if you want to trade based on that data or make decisions then you should directly check the price from where you want to do the trade.
also the fastest way to check the price for me is preev.com

impossible!
price needs to be corrected in order to rise with a healthy rate. LTC price went from 0.004 to 0.008 and it had a correction then from there to 0.01 and then up and down between that price and 0.009 because of some manipulation and after the recent rise we had some new correction (big one) and it will continue being so until 0.03BTC, 0.05BTC and so on.
i am guessing rise from 0.01 to 0.02 with little to no stop then a correction back down then rise from there.

i don't know if you are joking or what but this is not 100% correct. bitcoin demand is rising, and this demand is in very different forms.
yes most of it is in form of traders accumulating bitcoin, knowing it is limited supply and price will rise and they want a big ass profit in a couple of years from now when price is five digits!
but a big part of it is also because many are seeing bitcoin as a decentralized cryptocurrency that nobody can control. they get a good level of privacy and reaching anonymity with bitcoin is also a possibility. so they use it also as a currency.

and this:
is nothing more than your personal guess!
there is no easy way of proving this but we can see the different merchants that start accepting bitcoin every day, we can see the volume that is going in and out of a payment processor like bitpay (which has been growing with a fast speed each year by the way). we can also see countries like Japan adopting bitcoin as currency and other countries talking about it.

i will add the bitpay charts here if i can find any updated version of it for 2017.

EDIT:
and that is just Bitpay (a third party bitcoin payment processor working with a small portion of all bitcoin accepting services) and in 2016 their numbers have doubled and it continues growing processing 200,000+ transactions per month.
now consider all the other smaller and big services accepting bitcoin "directly". and this is the demand that i was talking about and it is growing.

it is funny a year has passed and ether has still not made up its mind about its unlimited supply. LOL

for someone who wants to day-trade, yes you can say with about 60% certainty that this price is high, so it is best not to buy right now and wait for a dip or wait until you can increase your 40% certainty.

but for someone who plans on investing in bitcoin for long term and not to trade, then this price is super low.
and for someone who plans on using bitcoin as a currency, then this price or any other price doesn't even matter. (although OP seems to be more like a panic seller who is going to buy at $1320 then panics and sells at $1318 and buys back at $1325 and a couple more panics like this then he goes away, i hope i am wrong)

if you don't exactly want "chart" but results, then it shouldn't be a hard thing to do. because it would just be analysis of some data that you receive. the hard part is to implement a GUI that represents this as a chart with lines and analysis and everything.
for example you can take the OHLC data from poloniex and analyze it and come up with a coin that has gone up 10x volume in your desired period.

if you are not a programmer just pay someone to make something light for you.

that "philosophy" has always been an speculation. and speculations can be wrong, they never work 100%, if they were working that way, those who speculated then would have been multi-millionaires in a day or so.
and when it comes to speculating about altcoin market which is fake and pump and dump, you can't be certain about anything. one day you see everything moving logically and make decisions based on that, the other day you see all logic is broken and things are moving in weird directions.
the only thing we can do is to hope for the best and catching the ride before it ends and getting off before it ends too.

if you know how to become successful in a business then you don't really need that much time to get there. obviously it takes time but a couple of months is more than enough to establish the business and become successful, then grow it from there.

it is perfectly understandable to be honest
there is a huge market with a lot of profit that is also easy to make. you just code and then premine, ICO, crowd-funding, or whatever else you want to call it and then release the code and people pay for it and you get rich.
although i am a bit disappointed to see someone like Cohen do this. i hope i am wrong about my assumptions.

of course it is a game! but it is not worth staying in it when you can get out on top and then buy back when it dumped.
i got in last month around 0.015-0.018 and then started my dumping on 0.04 up to 0.05 and have been staying away ever since.
- if i see another dump i will surely get in.
- if i see them release another public fooling thing and start pumping it then i will get in
- if i see bitcoin price dip again and them start their FUD about replacing bitcoin then i will get in.
- but i won't get in while we are still seeing it overpriced!

this is not a 100% thing but in most cases the following is true:
in short term it all comes down to bitcoin price. specially when altcoins are being traded against both bitcoin and USD.
let me explain with an example:
lets say BTC is $1000 and ALT is $10 ie 0.01BTC
if bitcoin goes up to $1200 that ALT remains at $10 there is no reason for it to rise up in USD value so the BTC value goes down to 0.00833333BTC and since majority of users are trading in ALT/BTC market they only see that dump from 0.01 to 0.008 and the sell pressure and panic sell starts and price gets dumped more. down to 0.0075BTC=$9

(this is the reason for LTC's dip in the past 24 hours from 0.0125 to 0.0114. and also why pumpCoins like ETH and Dash are getting dumped hard whenever bitcoin rises, also the reason why they started pumping right by the time when bitcoin dipped below $1000).

in long term, there is still an ongoing accumulation phase going on with LTC and the dip was actually a good time to buy more coins. and SegWit with its 100% support will activate in the next period and we will be on our way up.

this is a very good advice and i say it is even good enough to be stickied in the speculation board or something.

i have an additional though, which may be not so newbie friendly but good to keep in mind. and that is the fact that a coin dev being shit or not doesn't matter when it comes to making a short term profit from a pump. we all know most altcoins are pure pump and dump and it may be risky but figuring this out and finding the right time to get in (before the pump) can always lead to good amount of profit, and that is what we are all looking for.
so i say it all comes down to the market and traders. if they decide to pump a shitcoin they will and there is a lot of profit to be made.

i am not using it myself but it belongs to the same company owning Coinbase. it is not the best place to trade but it is good enough if you are looking for a trusted place (not 100%) to trade bitcoin fiat and a couple of other altcoins.

neither polo nor bittrex have fiat markets. they are all bitcoin versus altcoin markets.

even if it was possible, who in his right mind would want to do that! USDT price is currently -9% under $1 meaning it is worth $0.91.
and this is while you CAN withdraw bitcoin and sell it in another exchange.

it seems like you have never looked at any API documentation page ever and never used any bot for trading.
here let me help you a bit.
here is the link to the API doc page: https://yobit.net/en/api/
here is the order you need to execute:

and here is what the bot receives as an answer when you try to execute this order through API:

shall i post this again: https://bitcointalk.org/index.php?topic=1868467.msg18581813#msg18581813

let me give an updated version for last week:

well it is a fact that we live by and people either learn to take advantage of it or stay away because they think it is "immoral"!
in any case, pump and dumps and manipulations are happening in altcoin market and mostly because it is a very small market that you can easily manipulate and it is populated with lots of newbies who will easily give their money to you themselves without much effort on the manipulators part.
we can see a lot of topic of people even looking for scammers! topics like "where are the pump groups"

that is a good point but i think there are more things at play that we are not aware of for the time being.
i agree about what you said, and why they add certain coins and not others but in the end even coins that they can not pump themselves can give them profit! if a coin for example has a large daily trading volume, then that is a lot of trading fees that they are simply missing out on, and we are talking about a decent daily amount of money not a small amount.

Mt Gox was a tiny bit similar situation not at all the same. i have already said the differences and i am not going to repeat them again. but i would like to mention here that Btc-e has also been hacked back in 2012ish and lost a lot of money but they are still functional and working fine as before.
