Intuitive UX, focuses on the key features for trading, requires an Poloniex account, no fees. Cryptoriot is definitely my top pick for trading cryptocurrencies with my Poloniex account. You just have to fill in your API key from your Poloniex account and you're good to go. Trade all the Alt-Coins you want to with an visual an intuitive interface. You have an overview of your trades. This app really focuses just on trading without the other stuff with is not helpful (talking about candles). Feedback is taken very serious since this is a pretty new app. Try it out, its worth it!
UPDATE: I do not recommend paying to enter a Cryptocurrency mastermind group – I’ve tried a few and found the ROI to be disappointing. I am now focussing on growing my portfolio passively utilising a cryptocurrency trading bot, the renowned Notorious Bot. Having a bot that trades for me, without emotion, using an advanced algorithm, allows me to grow my portfolio in the background without it cutting into my time or stressing me out. You can familiarise yourself with the basics of cryptocurrency trading bots here. 
PentaFund is an actively managed fund (as opposed to passive investment funds, such as the Vanguard 500 index) made up of cryptocurrencies, blockchain assets, and traditional assets. It applies modern portfolio management principles to the world of cryptocurrencies. Arbitrage, leverage, short selling, hedging strategies, derivatives, as well as technical, fundamental, algorithmic, and trend analyses are all used to take advantage of the growth and opportunities in the crypto space.

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%.
The technology behind Crypto Assets is called the Blockchain, which validates transactions and balances. It is leading a new wave of Internet application development, which I believe will ultimately form the backbone of a large proportion of the Internet over the coming years. I suggest you spend some time reading up on and understanding the blockchain. These applications tend to be decentralised, which means there is no single point of attack or ownership.
There are so many hoops to jump through to set up for mining and each coin has its quirks. The power of your machine and graphix card and your power consumption are all important. My friend mined for 8month Eth and only made couple of hundred bucks by time you subtract power useage etc. He already had a powerful machine used in film industry for video graphix just sitting around so he thought he’d put it to use over that time for a laugh and see what happened. It took many hours messing around to set up and occassionally nursing it over that period. Of course he had to use his machine also occassionally which compromised the performance.
Watch the Order Book. The order book (found on all exchanges) can give you a good sense of what buy/sell orders are “on the books” (sitting on the market waiting to be bought or sold). If you see a lot of sell orders at a certain price and want to sell, you may aim to sell under that price. Likewise, if you are waiting for the price to drop to buy, look at the distribution of other people’s buy orders. Just watch out for artificial buy walls and sell walls (large orders that aren’t meant to fill). You’ll almost always find buy walls and sell walls at support and resistance levels.
Ethereum ETH, Monero XMR, Factom FCT, DASH, are all leading coins and traded the most volume daily. You should follow the coin’s chart and identify low and stable periods. Such periods are likely to be a consolidation period by the whales, and when the right time comes, accompanied by a good press release of the project, the pump will start and they will sell in profit.

I’m not going to go too deep into other ways you can earn money with cryptocurrencies because I don’t do them myself. At least not right now. Passive income is great. After you make an initial investment, you mostly sit back and watch the money roll in. It’s like buying a home and renting it out - there will be some maintenance issues but it’s mostly passive income.

To be able to take short positions, we need to understand margin trading. Trading on margin means we are trading with borrowed money. On exchanges like Poloniex, we can trade Bitcoin with a handful of coins (there are fewer coins offered for margin trading) with 2.5x leverage. That is, if we own 1 BTC, we can borrow up to 2.5 BTC to trade with. To be clear, this is not 2.5 BTC that we own. Now, on a trade that nets us 10% profit, we are bringing home .25 BTC instead of .1 BTC.
For takers, fees range from 0.10 to 0.25%. There are no fees for withdrawals beyond the transaction fee required by the network. One of the unique tools on the Poloniex platform is the chat box which is constantly filled with user help and just about everything. Any user can write almost anything but inappropriate comments are eventually deleted by moderators. It can sometimes be hard to distinguish the good advice from the bad, but the Chatbox is a great tool that will keep you engaged.
Only invest what you can lose. During the recent crash in January 2018, hobby-investors got burned. Reports of frustration and losses came at the cost of broken monitors, smashed laptops, and heavy monetary losses. While the rules are in more particular order of importance, it’s safe to assume that this is the most important rule, the rule to rule the rules. As soon as your money is converted into cryptocurrency, consider it lost forever. There is absolutely no guarantee you can get it back. Losses don’t simply come from dips in the market; extraordinary factors such as hacks, bugs, and government regulation can mean you’ll never see any of your money again. If you are investing money you can’t afford to lose, you need to take a step back and re-evaluate your current financial situation, because what you’re about to do is an act of desperation. This includes: using credit cards, taking out mortgages, applying for loans, or selling everything and traveling the world (as glamorous as that sounds).
