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!

I wrote the following simple guide to investing in Bitcoin and Crypto Assets back in Jan '17. After publishing version 3 of my strategy I felt a need to review and update it to reflect any changes in my approach, but upon review, I found very little needed changing. If you are new to Crypto, take your time to read this and the strategy, if you have any questions then feel free to get in touch, and I will do my best to get back to you.

While all features and services of the CryptoExchange platform are free of charge, cryptocurrency transfers from or to an external cryptocurrency wallet will cost the users 0.2% of the transaction and a minimum of ฿ 0.0007 (BTC), 0.007 (ETH), Ʀ 0.03 (XRP), Ł 0.0015 (LTC), Đ 0.01 (DASH) for the main Cryptocurrencies, when transferring cryptocurrency to an external wallet. Other than this, exchanging crypto to crypto and fiat to crypto will cost the users 1% and 5% of the transaction respectively.
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.
The best cryptocurrency for long term investing is CAS Token because you get more than a coin; you get a cryptocoin that is backed up by an ongoing strategy to support the online marketplace and a cryptocoin that is a hub for every other currency. Cashaa is becoming the backbone of the online financial world and you can make a lot of money by investing now.
You’ll find that different exchanges cater to different markets. Today, most countries have at least one cryptocurrency exchange specializing in their own currency. There are exchanges that can accept New Zealand Dollars in exchange for bitcoin, for example. Other exchanges are known for certain pairs. Bithumb, for example, has particularly strong liquidity in the ETH/KRW (South Korean Won) pair at the moment (and it’s easily the most popular cryptocurrency exchange in Korea).
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. 

Don’t zoom in too much on the price trends of the moment; don’t sweat the small things. It’s easy to zoom in and get stressed when Litecoin goes from $220 to $213 (or something like that). However, these little movements only matter if you are day trading large amounts of coin relative to your total investable funds. Zoom out a bit and look at trends over larger periods of time. Don’t think of that $213 relative only to $220, think of it relative to the $100 Litecoin was at a few months back, the $400 it was at after that, and the $100 it was at just a little while ago. From that perspective, a fluctuation between $220 and $213 is nearly insignificant. I will rarely make trades on timeframes shorter than 2hr candles, and I generally am looking at 6 hr and 1 day candles, because I value my sanity and am focused on the long term trajectory of crypto. That only changes in very specific instances and with purpose. If you zoom in too much, you lose sight of overarching trends (many of which are actually stronger indicators of what is actually happening).
Don’t invest blindy. There are people in this world who would sell a blind person a pair of glasses if they could make money. Those same people play in the cryptocurrency markets and use every opportunity to exploit less-informed investors. They’ll tell you what to buy or claim certain coins will moon, just to increase the prices so they can exit. Due to the highly speculative nature of the cryptocurrency markets today, a good investor will always do his or her own research in order to take full responsibility for the potential investment outcome. Information coming from even the best investor is, at best, great information, but never a promise, so you can still get burned.
