Remember, cryptocurrency is volatile! There is always the chance that the market will crash. Cryptocurrency isn’t a centrally controlled and regulated fiat currency. Even though blockchain is connected with a feeling of security for most people, a 2-factor authentication is used, if you lose a coin or someone cheats you, there is still nothing you can do about it.

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.
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.

The basic idea of this strategy is, “get out until the carnage is over.” When the crypto-market is under fire, non-crypto assets will appreciate in value compared to cryptocurrencies. Moving some of your portfolio over to fiat currencies (or something else) will protect it from a declining cryptocurrency market. This is similar to how investors buy gold as a safe haven in times of stock market turbulence. When the storm is over, you can buy back your assets at a lower price. It’s always a good idea to keep a diversified portfolio.
For instance, you might have a day trading strategy that exploits differentials in tightly correlated cryptocurrencies: BTC and ETH, for example. If you think that BTC and ETH are tightly correlated and you see that ETH is disproportionately low, you might buy ETH with the expectation that ETH will rise up again to restore its typical relationship with BTC. However, this might be a case of contagion: the whole market is going down. In this case, your technical analysis could be your downfall: you’ve just bought into a position that’s still going down.
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 have been following the crypto markets since mid 2017, just in time to witness the incredible surge of the digital asset industry. Fascinated by the potential of blockchain technology I’ve started to dig deeper and that’s how I ended up meeting the Toshi Times team. I hold a Political Science degree, therefore the crypto regulation development is particularly interesting for me. I’m also heavily involved with music, running my own label, a YouTube channel and working with distribution. People call blockchain the ‘Fourth Industrial Revolution’ and I believe it will change our daily lives in the coming years and we will have the front row seats to witness it.
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.
Remember those candlestick charts we see on every exchange? By studying them, we can find indicators, and understanding what these indicators mean can help us better predict the future price of the chart. There are tons of indicators and they can take some practice to become adept at identifying. You may find it easier to focus on practicing to identify them one by one until you become comfortable with them, slowly building your repertoire until you feel you’re ready to go full boar with your trading career.
The only apps that can do trades right now are the mobile apps for the various exchanges. And to view the market and coins available, the most popular site/app is Coin Market Cap. But there really isn't one that can handle everything for you. Which is why I'm currently building out an app called Matrix Portfolio, that will help you automatically pull in your trades from exchanges, so you don't have to manually enter them. As well as allow you to discover all the coins, and offer trading insights as well. Feel free to pre-register for the beta here:
Before buying into a position on an exchange, it’s probably prudent to consider whether there’s enough liquidity to make a well-timed exit. Day trading is all about timing one’s trades, and many cryptoassets and exchanges don’t have the liquidity to support the near-instant trades an experienced trader might be accustomed to in trading stocks or forex. Consider checking the 24-hour volume of the asset, and verifying that the exchange allows you to both buy and sell the asset — some only allow you to buy, and some that allow you to sell might temporarily turn off selling at times of high volatility.
The cryptocurrency market is insanely volatile in 2018. You can make a fortune in a moment and lose it in the next whether you trade Bitcoin, another coin, or the GBTC Bitcoin trust. Consider mitigating risks, hedging, and not “going long” with all your investable funds. TIP: If you trade only the top coins by market cap (that is coins like Bitcoin Ethereum), or GBTC, then the chances of losing everything overnight are slim (not impossible, but slim). Other cryptocurrencies are riskier (but can offer quick gains on a good day).

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%.
Don’t get itchy fingers (AKA be wary of FOMO buying). As noted above, if you have a strategy, stick with it. Sometimes the market will go nuts, and you’ll see epic gains, and you’ll get FOMO (all humans get FOMO, it takes discipline not to react to it). Selling or buying at that time may make sense, but don’t get nervous and switch up your whole strategy without thinking about it. That is often when bad moves are made. If you are going to buy heavily or sell heavily on a whim, consider taking a step back first.
Investing in any currency is an activity that, roughly speaking, can be done in two ways: the speculative, by means of short sales (buying and selling currencies several times in one day depending on the possibilities of the price going up or down), Or by developing a medium- or long-term investment scheme (i.e buying currencies and saving them for a longer period to sell them when appropriate).
What would be a good portfolio for a newbie today, I just keep losing with these popular Altcoins? Are you seeing just as much significant growth today (like doubling) as before with your portfolio? I need a fresh portfolio today that has just as much potential as the day when you had bought into your Altcoins. Can you also give an idea of the percentages of the spreads you mentioned in your wallet? Also, with the influx of coins/icos, do you think alot of coins will lose value and it will be harder to find the gem amongst the rocks?
In 2017 Crypto Markets Continue to Trend Higher with Momentum It is evident that cryptocurrencies have been in a trending market for the past two years, or some would argue, since their inception. Every $1000 invested into a basket of Bitcoin, Ethereum, and Litecoin at the beginning of January 2017 would nicely turn into $18,000 in just 11 months; completely…
Categorize your investments and look at the long picture. In the process of your research, you’ll eventually realize you’re coming across a few different categories of coins. For some of them, you believe they have good teams, great vision, amazing publicity and a track record for successful execution. Great! Put these into medium or long-term holds and let them marinate into a delicious tenderloin. When the price dips, don’t even consider panic selling because anything in your medium or long-term portfolio should remain untouched for a set amount of time. BNB is a good example of a coin Miles considers a long hold. Recently, it dipped 20% for a while, and within our community, we witnessed some sell-offs to preserve investments. A week later, it jumped up almost 3x for a period of time.
