If you have an account on Poloniex.com or Bittrex.com (and other crypto exchange sites) you can use their API with TabTrader to easily trade and monitor prices on your phone. It's important to me that the app connects to Poloniex and Bittrex because these exchanges have good volume. And they're pretty credible. TabTrader supports other major exchanges too :)
How often will you buy or sell? Some people want to be day traders, but we’ve shown that holding could be the best bet. The general rule of thumb is that the longer of a time horizon you plan on holding for the less risk you incur. This rule carries over into the realm of cryptocurrency from stock investing. However, here may be times to simply cut and run. Declines due to unforeseen structural issues are an indicator to cut losses and sell out.
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.
When you buy/sell via an exchange, try to use limit orders (try not to use market orders). On some exchanges, like GDAX, limit orders have lower fees than market orders. On GDAX, limit orders are free as long as they don’t fill immediately. Meanwhile, market orders result in a .3% fee, which is better than the 1.4% that Coinbase charges but not as good as 0%, especially if you are day trading. If your exchange rewards you for using certain order types, aim to use them.
A long-term investment is one where you expect a cryptocurrency to perform better over a longer period of time. Simple! Normally, the minimum time for long-term investment is 6 months to 1 year. Although, some people plan to hold onto their investments for 5-10+ years. It’s up to you how you choose to invest; you can either make your full investment in one go, or you can invest at different times.
Bull markets, bear markets, corrections, and bot manipulations.  All part of the cryptocurrency trading world that has gotten people so interested in trading crypto and being part of the game that’s sure to change the investing world forever.  These new markets are right now looking for new investors, but how to invest if you are a beginner?  Here are some cryptocurrency trading strategy tips.
Congrats @nicolasvh and the team at Opus Labs - this has to be one of the top hunt's of the year IMHO. I'm heavy into crypto HODLing, trading and watching and have tried EVERY crypto tracker available for iOS. It's pretty simple; no trackers come close to Blockfolio, until now. Delta is the first app that has seriously challenged Blockfolio. Even if the team doesn't grow the feature set, it is hands-down better than Blockfolio, both in UI and functionality. Add that to the upcoming features that Nicolas mentions in the last paragraph of his intro and this app is OFF THE CHARTS!
Trading on low-volume days in the market could incur substantial slippage. People who make trades — especially large trades — on low-volume days often will not find many partners on the other side of the order book willing to make that trade. The result is that they could end up paying much more for the trade than expected, incurring slippage in the process.
Sure, many lose a lot of money during the panic of a cryptocurrency crash or sell off. But, those that know what they are doing have the range of tools needed to make big profits during this time. Here are five of the best ways to turn a profit during cryptocurrency market turbulence, and how you can easily leverage all of them at once in order to make the most out of the current market opportunities.
Keeping up to speed with the news on Cointelegraph, seeking independent ratings on ICOs, and gathering as much information as you can on a coin’s background are essential steps before you decide to make an investment. After making a purchase, monitor any changes in price closely – and consider setting higher and upper limits on when you would want to sell your crypto, mitigating losses in the event of a crash and protecting profits after a surge.
TIP: A cryptocurrency wallet is a place where you store encrypted passwords that represent coins (the equivalent to storing money in a bank account). A cryptocurrency exchange is like a stock exchange or like a currency exchange in a foreign airport (a place people can trade cryptocurrency for other cryptocurrencies and fiat currencies like the US dollar). Just like if you want to trade stocks you need a bank account and access to the stock exchange, it is the same deal with cryptocurrency.
Like any other loan, this borrowed Bitcoin must be paid back with interest. On losses, you will need to pay back the loss and the interest. Poloniex offers up a great guide to margin trading that explains everything you need to know. It’s worth reiterating that the estimated liquidation price is the price at which a forced exit from our position would occur, costing us all of the Bitcoin in our margin account so that it may be used to pay back the borrowed coin. Utilizing stop limits to avoid this is almost always a good idea.

Hold some coins, range trade some coins, keep money on hand for a dip, and set some high-ball and low-ball orders. If you want to ensure you are happy no matter which direction the winds blow, then be set-up to benefit from whatever comes next. If you have some coins you hold, some coins you trade daily or weekly, some money set aside for a dip, and some high-ball and low-ball orders set, then you stand to benefit regardless of what happens. It can be tempting to cash out of crypto or go all in, but both of those can be disappointing if the market goes in the opposite direction you were hoping for. It isn’t always the most profitable move to run a strategy like this, but it can help you to gain experience and have something to be excited about in almost any market. TIP: Note that diversifying your strategy and holdings eats into profits, but offers flexibility. It is a trade-off.
In order to keep your crypto investments safe, you can keep your records in a separate hardware wallet and keep a track of your trading stack. Features of some cryptocurrency exchange platforms may vary from other platforms and that’s why it is important for you to find the one that matches your needs. Once you are sure about the exchange that fulfils your requirements, go ahead and trade.

On top of that, the cryptocurrency market travels at lightspeed compared to other markets. New coins enter the market on a daily basis (in 2016, there were about 550 different coins, today there are about 1,500), and each one has news every day. I’m not doubting your ability to consume and analyze news, but that level of information bombardment will always be more effectively consumed as a group. In these communities, you’ll see members link news and relevant articles about coins you’ve invested in and coins you’ve never heard of. The community will definitely expand your knowledge much faster than doing it all yourself.
