When buying coins, and especially with Bitcoin, you will notice that your purchase is in decimal. A Bitcoin itself is relatively expensive, around $10,000 at the moment (as of 15th Feb '18). If you were to purchase say $5,000 of Bitcoin, you would at today's rate be purchasing around 0.5 of Bitcoin. Do not ever worry about this; Bitcoin operates at eight decimals places. You do not need to own a whole Bitcoin or any coin for that matter. Consider it like pence in the pound or cents in the dollar, but with more decimal places.
At this point, you have narrowed down your list to a few cryptos that have a good potential for profitability. But you need to narrow down further and find the ones that have the potential to take-off faster than the rest. That’s why you need to keep in touch with the news.  Check out crypto news from different sources to determine, which of the cryptos you have in your bucket-list have some interesting news coming up.
Similar to Bitterex, Poloniex is also a crypto-only exchange which will allow you to go ahead with your trading by depositing Tether dollars. The fee charges for this crypto exchange depends upon your choice (whether you are a maker or taker) and can be 0.15% to 0.25% accordingly. Traders looking for a variety of altcoins can check Poloniex for their requirements. Although you’ll get an intuitive mobile-friendly website to place your trade; there are no options in terms of mobile applications.
I prefer to trade on decentralized exchanges. For myself, I made a choice in the form of ethnermium.сom. They have a huge number of coins. There are no minimum restrictions on trade and fees are so insignificant that you will not notice them. I also think the advantage of the easy creation of a wallet like MeW and easy integration with metamasks and a high level of security
Crypto exchanges no longer serve a small community of early adopters, but an entire market of crypto enthusiasts that just can’t get the level of service they are looking for when trying to exchange cryptocurrencies. Introduced by the same people who brought AAATrade to the world of CFDs, CryptoExchange is a relatively young cryptocurrency exchange that has gained popularity among crypto enthusiasts these days. The platform aims to resolve the hassle associated with the slow approval process and poor customer support that characterizes traditional exchanges.
I see price plummets and sky rockets and I’m tapping “please please please!!!” Quietly screaming into the phone HURRY THE FUCK UP!!!! But there is no response or freeze and lag. It happened on my Windows laptop last night and now Android. I am beside myself with frustration! And the charts do NOT match the market price for longer than a minute after I refresh the damned thing. And taking the time to do that means missing the buy/sell scroll. Everyone craps on Poloniex, but the few bucks I have over there can get traded in a timely manner if I use the buy/sell scroll instead of making my own offers.
I’m not going to lie and say I didn’t want the job anyway. I did want it. But I also feared losing my freedom. I’d be working more for less money and less flexibility than I had while running Bitfountain. Gone would be the days where I could spontaneously book a flight to India with no return date. No more of the four hour lunch breaks that I’ve come to cherish over the years.
You could try this instead: Be sure to keep reading crypto news and price analyses — not just staring at charts. Even though you shouldn’t give in to the FOMO and FUD generated by many crypto articles, you still need the news in order to stay apprised of market conditions. Also consider setting stop-loss orders to ensure that your losses will be mitigated in the event of something like contagion. 
I bought Elastic $XEL at the obscure Heat exchange. It was rather difficult discovering how to buy it because I was in this case ahead of the herd where the path was not well defined. In the end I bought it at a high price (average 31,367 Satoshis, should have got them at 25,000 Sats) as I got scammed over at Heat by a predator (Arsonic @Ars0nic on Twitter) playing the order book. We’ll see how that plays out. I think the excessive price I paid will not matter too much.

If you are going long, consider building an average position (for example via dollar cost averaging or value averaging). There is no better way to avoid making a poorly timed trade than buying incrementally instead of all at once and thereby buying an asset at its “average” price over time. If you don’t have a really solid grasp of technical indicators and the way the volatile crypto markets work, consider averaging out of positions as well. Averaging isn’t just financially conservative, it is important psychologically. Taking too big of a position at once can be emotionally difficult to deal with (and can thus lead to bad decision making) given the historic volatility of the cryptocurrency market.

Before committing to a trade you'll always need to answer a set of questions like: What is the target for this trade; Where to sell; What is the position size; Where is the stop-loss; Is this a short or a long-term investment. With Crypto Trade Academy, you'll not only learn to ask yourself all the right questions. When you complete our training, you'll know how to answer them each time you'll start planning a new trade.
Understand blockchain – You don’t need to understand the technical complexities, but a basic understanding will help you respond to news and announcements that may help you predict future price movements. It is essentially a continuously growing list of secure records (blocks). Cryptography secures the interactions and then stores them publicly. They serve as a public ledger, cutting out intermediaries such as banks.
All of the different techniques used to track the price of Bitcoin and other currencies have one common factor- they require investors to remain up to date on the latest market movements. In addition to keeping track of the cryptocurrency market, it’s also necessary to buy and sell on an exchange, select a Bitcoin wallet, and make analytical interpretations of the statistical data gathered during market observation.

In the beginning when I was shooting for 20% gains on a trade and not knowing what to look for, I worked a lot more. Not only that but I also let my emotions control my trades. For example, I once purchased Stratis after the price dropped massively. My assumption was that on such a sharp decrease in price, it had to rebound eventually. I was wrong. The price kept diving. I had to hold the currency for 2 weeks just to secure a 35% loss instead of an 85% loss. I was constantly tuned into that chart waiting for an opportunity to sell back to Bitcoin.
In 2015 and the beginning of 2016, when Bitcoin held solid – as solid as Bitcoin can be – shuffling around $300 per one BTC, the game was trading Altcoins in order to gain more Bitcoin. It was expected that Bitcoin would grow higher in the future (the Pygmalion effect). Having a rather volatile base asset, such as Bitcoin, raises our need to compare our portfolio performance both in terms of its Bitcoin’s value and its dollar’s value. Many traders decreased the number of Bitcoin they are holding during the past year (hey, and it wasn’t hard when Ethereum got cut 70% from its Bitcoin all-time high…) although it had a nice dollar yield. Bitcoin’s growth made a lot of money for the crypto market, causing its total market cap to increase 30 times during the last year! As traders, it is important to keep Bitcoin as your base asset, but also not to forget the dollar value, and to take profit sometimes. You should always see the bigger picture – crypto is only one tier of your investment options. There are also the stock markets, real estate, bonds and many more investment opportunities. It is important to spread the risks among the crypto portfolio, as well as in the whole household investment portfolio.

A common beginners’ mistake is to look at the coin’s price rather than the market cap. Just as you asses a company by its market cap performance, which is calculated by multiplying the number of shares times a single share’s price, the same is done for Altcoins. The number of existing coins in circulation times the coin’s price. For a low price coin, such as Ripple, there is solely a psychological influence on the buyers. There is no difference whether one Ripple equals one dollar, and there are a billion Ripples out, or if one Ripple equals a thousand dollars and there are million units of Ripple. Therefore, from now on, when examining coins for investment on CoinMarketCap, look mainly at the more substantial figure, which is the market cap, and focus less on the price for one coin.
Maybe you remember when, thanks to The Wall Street Journal, everyone thought the SEC was going to meet on May 7th to decide whether or not Ethereum (ETH) was a security. If you had taken up a large position in ETH prior to the 7th, you would have been disappointed when the price fell from ~$793 USD to ~$743 USD amidst news that there actually was no meeting after all.

In this complex chart, you can see the current Bitcoin prices in the upper third. The green lines indicate a rising price, red lines indicate a falling price. The thin blue threads above and below the candle-shaped price indicators are the Bollinger Band. If the candle touches the top, then the value is “overbought” and will likely fall. If it touches the bottom, then the value is “oversold” and will likely fall.
