Ideally, a rookie trader should start by choosing a reliable exchange and playing with popular coins, such as Bitcoin or Ethereum. However, the learning by doing approach is too slow for those who want to succeed fast. Joining a community of like-minded traders could be one of the best decisions to make: there are plenty of groups on Telegram or regular meetups in the US and other countries.

Trading strategies are there to provide objectives for traders to earn more with lesser capital; just like how a successful business should operate. There are a lot of trading strategies that are being written all over the internet today, but what we’ve noticed is that most of these so-called “strategies” are just plain common sense; something that is hard to come by nowadays.
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.

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!
If your focus is to conduct crypto-to-crypto trading, Binance is one of the best options. Ranked as one of the most popular cryptocurrency exchanges worldwide, they provide you with impressive offerings along with an extremely low trading fee. Although the Binance platform is a young entrant into the market, it is rapidly growing, and holds a huge selection of altcoins with Bitcoin, Ethereum, and Tether pairings.
Blockfolio is an extremely powerful digital currency investment tracking app that is ideal for individuals that hold an extremely diversified portfolio. Operating diverse portfolios can often be unwieldy and, due to their cumbersome nature, require constant scrutiny and management. The Blockfolio app has been specifically designed for highly diversified investors, and streamlines the process of tracking where and when you bought and sold, as well as the value of your current holdings.
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.
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.
