A “manageable amount” is obviously subjective and will vary for each person based on things such as time available to dedicate to trading. Feel free to do your own research to find the right exchange for you. I tend to value user experience of an exchange over the amount of coins on it. Ultimately, what exchanges you use is going to depend on your own personal preferences. GDAX and Poloniex will provide sufficient resources needed to be a successful trader, so they are definitely a good place to start.
Great manager, research tool, social chats, charting and just plain fun to use. And all this is in version 1.0. Yes it costs a fin, but, if you really want it and can't afford it, yet promise to give me suggestions I will get you a coupon. Just contact me. We are very proud of our first foray into the cryptocurrency space. We just know you will love this app.
Dollar-wise, as you can see – Litecoin’s price has increased along with Bitcoin (but less). A reminder about the majority of those quoting “Bitcoin has increased greatly, I’ll buy Litecoin”, buy Litecoin with FIAT (or by converting to Bitcoin, then to Litecoin right after – which is the same). Therefore, learning from the graph yet maintaining the same behavior, when Bitcoin’s value drops, Altcoins’ USD value will drop as well (although as a percentage it will probably be less, but it will still go down).
Once you have narrowed down on cryptos with high daily trading volumes, focus on their historical price movements. The best way to do this is to use a financial ratio known as the Sharpe ratio.  Don’t worry about calculating it, since you can easily find it online.  The Sharpe ratio measures the potential return of an asset based on its volatility.  Figures higher than 1 are usually a sign of an asset with high potential returns. Given that cryptos had a stellar year in 2017, most of them have a Sharpe ratio of higher than 1.  Therefore, for you to make use of this ratio, narrow down on cryptos that have the highest Sharpe ratio relative to the rest of the market to Profitable Cryptocurrency Trading

Identifying stop loss levels to minimize losses:  In the order book we identify the points of support that we also analyzed before. It is likely that being supportive, massive demand (a “wall” of buyers) is present around those spots. This is the best zone to place the stop loss command, although it should be placed a little lower than the high demand zone. They will only get to our command if the sellers manage to lower the price and the “wall” of buyers breaks. The “wall” of buyers works as a sort of protection level for our command.

Market orders allow us to exchange any amount of coin right away at the current market price. Orders are filled using the best available price in the exchange’s order book. For example, if you placed a market buy order for $100, it would buy from the lowest priced sell order(s) until you had used that $100. The advantage is that this transaction is always completed immediately; the disadvantage is that we don’t know exactly what price we are going to get.
The crypto world is a uniquely perfect environment for arbitrage. As William Belk argues here, the combination of it’s distributed nature, regulation, security, availability, and anonymity factors means that the marketplace has many inefficiencies, and that “arbitrage opportunities will continue indefinitely.” For example, some markets pay a premium for security, geographical location, or simply because they don’t know they can get it cheaper somewhere else. In some cases, the price discrepancies across different exchanges can be as much as 43%.
Sometimes, it can be easier to enter a position than it is to exit that position. Certain exchanges are fairly illiquid: they don’t have enough buy orders to support easily selling off your cryptocurrency at a good price at any given moment. At other times, exchanges that usually have healthy liquidity might have really low trading volume — for instance, if you’re trading on a holiday or weekend.

The cryptocurrency market is very well known for one thing, and that is volatility. The price of Bitcoin, or any given cryptocurrency can rise by 20% in the span of a few hours and just as easily fall by another 20% in the next few hours. Ultimately, some traders use this volatility to try and turn a profit. One such strategy that allows for this is swing trading.
NOTE: Once you have Coinbase down, try moving onto GDAX. It’s, in overly simple terms, like a better version of Coinbase with lower fees. Coinbase operates both platforms, and both use the same logins. GDAX is the preferred exchange of many Bitcoin traders in the U.S. It caters to both pros and novices. After you master that, then consider exchanges like Bittrex and Binance.
You need a trading plan. You can basically consider it to be a blueprint for success. Your plan has to take everything that you can into account like entry and exit of money, risk management, time frame and even position sizing. Without a plan and too much emotion, you will be gambling instead of trading and you will never know how to improve your skills to become better.
TIP: The tips and tricks below shouldn’t be mistaken for professional investment advice; instead this is basic friendly advice to mull over. If you want professional investment advice, consult a fiduciary. For a shorter list that zeros in on some key points, see: 5 Tips for New Crypto Traders.

Use small buy-ins, and don’t margin trade or short unless you know your stuff. The smaller your bet is compared to your total investable funds, the less risk you are taking on every bet (one of many insanely important things we are covering here). Putting it all on black is tempting, but then if it comes up red, you have nothing left to invest. Live to fight another day by learning to manage your buy-in size. As a rule of thumb invest 1% or less per buy-in (yes, that small, really; losing 100% of 1% leaves you with 99%, losing 1% of 100% leaves you with 99%. Small bids offer the same bet, but with way less risk). Put reward aside and practice risk management and capital preservation until you are very experienced (and thus, by logical extension: don’t margin trade or short unless you know what you are doing, as those leveraged bets magnify your risk by their very nature). See Kelly criterion.

Take a look at the screenshot. You can see there candlestick chart. In the upper part of the chart, you can choose indicators and different graphic tools. As for indicators, there are many useful algorithms including the most popular Bollinger Bands, ADX, ATR and the others. Graphic tools are represented by different types of lines and other geometric patterns. Here you can find Fibonacci retracement as well.

Investing and especially trading, is a highly skilled task. You need the best equipment, execution and tools. When the market is only going up any fool can make money but that blessed state never lasts long and what is left is an environment requiring focus, skill and discipline. To succeed unlike the devastated cohorts of dotcom and the real estate bubble, you have to work hard at it.

You don’t have to buy a whole coin. You can buy fractions of coins. Bitcoins are expensive currently in 2018, so consider buying fractions of a coin to start if you don’t have a big bankroll. It has historically been a mistake to buy only ETH and LTC because BTC costs more. You should consider which one is most likely to increase in and retain value. Buying all three in equal dollar amounts, and ignoring how many of each coin that amounts to, is one way to avoid making the wrong choice based on price tag per coin.
Always pay attention to Bitcoin. Most altcoins (every cryptocurrency except Bitcoin) are pegged more closely to Bitcoin than Asian currencies were to the USD during the Asian Financial Crisis. If Bitcoin price pump drastically, altcoins price can go down as people try to exit altcoins to ride the BTC profits; inversely, if Bitcoin prices dump drastically, altcoin prices can go down, too, as people exit altcoins to exchange back into fiat. The best times for altcoin growth appear when Bitcoin shows organic growth or decline, or remains stagnant in price.
