Burst coin is good coin and valueable burst was great chane in price it will gone up to 900 satoshi
BURST has a very strong and dedicated dev team.  That have substantial personal investment in BURST... so they are motivated to make the coin go.

I think poloniex and bittrex is best trading sites for all but great information for me about
Shapeshift.io
Gatehub.com

Sia coin is good valueable coin
Sia coin have good technology and good teamwork and also good in communication
Sia coin rate is now a days went down due to bitcoin segwet hype it will go up after bitcoin segwet

Sys coin is good [Suspicious link removed]d team good technology
There is good time to buy sys coin for long term trading you can get a good return for long time investment

Bitcoin word class top decentralized  currency at high price at current price every one now about bitcoin Big number of companies start to accept bitcoin as a currency there is too much rush in bitcoin transactions all other crypto currencies trade make possible due to bitcoin
Ripple is good coin have good technology
Ripple is used for banking purposes

Steller is good and value able coin have good technology and good working team
Str was touch the peak of 2400 satoshi in future it will touch pump again sooner
Good time to invest, there's a big possibility that the price will continue to rise.

I think One coin was start marketing almost 3 years before but until now one coin is not listed in any trading platform OneCoin has had not good reputation in the market and overall community.

Dgb is valueable coin and good technology and good team
I agree they had the ingredients for success they should be in the top ten long time because they have a good team behind them and a good roadmap too
DGB was touch upto 2400 satoshi this is segwet alt down trend after segwet it will go up.

My first investment was few 42 usd, and after few days they were 62 usd then after few days i were invest more almost .3btc there was some growth and I have few 1000 usd in alts. I were make a good profit but now i am in almost 50% loss due to bitcoin segwet hype. I will wait and will get a profit.

People buy altcoin because altcoins gives more profit lot of Altcoins are very low rate in satoshi and there are maximum chances to make a grest pump some time altcoin make a double or more and profit also double or more but but coin price make ups and down but not like altcoins like make double or more in short time etc.
I think thats way people buy altcoin to increase position in btc.

There are different ways to get updates
Twitter,youtube,facebook,reddit and also receive email of news letter.
But i think its not enough for observing pump and dump yiu have a good technical and fundamental knowledge and past experience and market conditions.

Btm - my first profitable trade
Pink - close trade in loss
Stratis - Will not invest
Doge - Earn good profit
Bcn - Earn good profit
List of Altcoins I am closely watching.
ETH
DASH
Digibyte
Ethc
Eth
SC
ZEC
NXT
XCP
XVG

this time is better than if you buy before few days almost 30 days when the down trend is start i were bought str and sia coin at high and i am waiting until the bitcoin will stable and also all market of altcoin will stable after that market will go up and sell in profit i think str and sia coins are good and valuable coins and i think they will pump and give us good profit.

Siacoin is mineable crypto currency have a good team and also good technology and have a good market cap of $185,689,400 the office of Sia developers is in Boston, USA Sia users and miners  are all around the world
Storjcoin is not mineable crypto currency have market capitalization of $18,733,516
Sia is more transparent, good team, good technology, has been in production longer. Sia for the best.

Altcoin price does not took a dip every time when bitcoin price goes up
I observe the main thing is the way how to bitcoin price go up if price of bitcoin make a pump for example the price pump up to 20% 30% etc. in one or two candles in an hour then the buyer feel hype and they sell altocoin and move to buy bitcoin and then price of altcoins goes down but if the bitcoin price grow smoothly for example 20% increase in 3 days or more while not a big decrease then altcoins have no effect.

I think don,t panic sale wait until price will go up
Xrp is good coin use for banking sector
Xrp have good market capitalization
Xrp have good Technology and good updates on social
Xrp is at good Rank
Xrp is valuable coin  maybe you would earn more in the future

Some peoples provide signal as per own experience some time they hit and some time signals not hit it doesnot work 100% every time i think the best way to trade in own knowledge and experience by understanding the market condition and coins information also.
You need to learn to study the movements of graphs, candlesticks, trending in trading etc.
 

When altcoin price down by bitcoin up traders are buying bitcoins and sell altcoin this make decrese of down in price of altcoins

Pinkcoin is a good option to invest i think buy this coin now at low rate 443 and i hope it will go upto 1000
after market stability.

there are lot of coin are go it down more then 50% down like
Xrp
Str
stratis
Eth
Ethc
Xcp
Sc
Nem
Xvg
i think these coins are good coins  to invest they almost too much down
and try to purchase at low trend of market and wait to pick at lower rate.
