Always pay attention to Bitcoin. Most altcoins (every cryptocurrency except Bitcoin) are pegged more closely to Bitcoin than Asian currencies were to the USD during the Asian Financial Crisis. If Bitcoin price pump drastically, altcoins price can go down as people try to exit altcoins to ride the BTC profits; inversely, if Bitcoin prices dump drastically, altcoin prices can go down, too, as people exit altcoins to exchange back into fiat. The best times for altcoin growth appear when Bitcoin shows organic growth or decline, or remains stagnant in price.
The first thing you need to do before you invest in a crypto is to analyze its trading volumes. As a rule, always go for cryptos that have high daily trading volumes, unless there are some big upcoming news about a low volume crypto. High volumes signal to a Crypto’s liquidity, and the presence of an active community. The problem with low volume cryptos is that in most cases, they lack a strong community backing them, and they can easily get delisted from exchanges, leading to losses.

What’s important to consider as crypto evolves is to learn everything (or as much as possible) for yourself. Crypto coins all offer white papers to the public (though they’re not always easy to find). They’re for a scientific audience, but you’ve probably read worse if you have a university degree. Find them and read them. Don’t understand something, ask a question.
I bought Elastic $XEL at the obscure Heat exchange. It was rather difficult discovering how to buy it because I was in this case ahead of the herd where the path was not well defined. In the end I bought it at a high price (average 31,367 Satoshis, should have got them at 25,000 Sats) as I got scammed over at Heat by a predator (Arsonic @Ars0nic on Twitter) playing the order book. We’ll see how that plays out. I think the excessive price I paid will not matter too much.

No one actually knows how long this whole crypto thing will last but instead of losing sleep at night constantly checking token prices which have zero fundamentals behind them, I’d much rather invest in a real business that will make money whether Bitcoin prices go up or down. (Full disclosure: To satisfy my own curiosity, I do own a tiny amount of Bitcoin which won’t make me rich nor will it affect me if the whole space goes to zero).
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!
Fundamentals cover things like crowd behavior and news flow.  Crowd behavior means that when the “crowd” is piling in while the price is of a coin is pushing upward, maybe you will want to ride the momentum (with caution as these people may end up getting trapped within it), or it could be a situation where everyone is in the thing and now the coin is seeing a downturn, and they are all trying to piling out.
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. 

Sub or Substratum is another open-source network with a huge focus on decentralizing the web and on “making the internet a free and fair place for the entire world.” This platform allows content creators to freely host their websites or applications on Substratum host, without any censorship blocks. Network users can then “run” Sub nodes and help the content get forwarded to end web users, who can access all Sub content in regular web browsers without any blocks or limits in shape of censorship.

Cryptocurrency is volatile! There is always the chance that the market will crash, or that you will face some other catastrophe. Cryptocurrency isn’t a centrally controlled and regulated fiat currency. If you lose a coin, or someone cheats you, or your account gets hacked, there is nothing you can do about it (which is one reason why you want to have 2-factor authentication set-up).

Only a few cryptocurrencies – such as Bitcoin and Ethereum – have achieved mainstream levels of popularity. However, even well-established currencies can fall victim to extreme price volatility. It can be difficult to predict how prices will fluctuate with newly minted coins because there is little historical information to analyze. Backing a new currency could prove extremely lucrative, but equally, there’s a chance you’ll make an expensive mistake if you don’t know what you’re doing.
Fiat Currency is still a thing; BTC isn’t legal tender; we don’t live in a Libertarian utopia; Governments and Banks aren’t as into Bitcoin as you. If you get caught up in the Bitcoin craze, it can easy to forget that the world’s governments aren’t super stoked on Bitcoin. Libertarians, Tech Geeks, Gangsters, these people are bullish on Bitcoin; world governments and banks, not so much. Last I checked, world governments had a little more power. Betting against them is a risky bet. As we move into the future states have started embracing Bitcoin and crypto, but there is no plan for a state-less state built upon digital currency. Digital currency is at best a supplemental asset class. Be realistic about the potential future here, it is bright, but it is likely not to look like your specific flavor of utopia.
On the contrary, bitcoin has been widely used for international payments and is way more efficient compared to traditional cross-border remittance. According to Mr. Smith, “They use Western Union, traditional banks; It is slow and it is expensive. And there are people that can stop you from sending that money, whether that’s good or bad. With bitcoin, I can send money. It’s fast. It’s cheap. And frankly, no one can stop me.“

I downloaded the app and under Fund management the first option is to bind bank card BUT THIS is only for Banks in China then the second Option is BIND ALIPAY , but I face issues when I enter my email account (alipay registered email acc) and click submit button nothing Happen. It says “PLS fill your own alipay acc” and “Click the view below and Upload the alipay code”, I fill my info and click to the logo of alipay but nothing happen like what it stated
This is not a get rich quick scheme. While returns can be good at times, I have seen periods of stagnation, five +30% market dips and a bear market. Whenever you enter the market, it could be on the rise, in a drop or be stagnating. I have also had days and weeks where I have seen a significant decline in my portfolio. I can't predict what the market will do when you enter. Please invest for the long term. This is much more volatile and risky than the stock market.
Ethereum: Well, the father of platform-oriented cryptocurrencies. Being a cryptocurrency, Ethereum does more to the ecosystem than almost all the others in the market. It’s Solidity program allows for excellent smart contract programming, it is also a platform where Decentralized Apps are built and deployed, and many leaders in the blockchain space, including IBM have used Ethereum’s smart contracts and platform to build and deploy applications.

Many governments are unsure of what to class cryptocurrencies as, currency or property. The U.S in 2014 introduced cryptocurrency trading rules that mean digital currencies will fall under the umbrella of property. Traders will then be classed as investors and will have to conform to complex reporting requirements. Details of which can be found by heading to the IRS notice 2014-21.
While these rules are by no means the only lessons you need, they’re definitely a great starting point. Sometimes, though, things are easier said than done, such as watching your portfolio value plummet and still having the iron willpower of resisting the sell button. One of the best solutions I’ve found to this was to join a community of like-minded cryptocurrency investors. Educated and smart crypto-traders, as well as the community members, will all be there to support your efforts and will be holding with you in the rough times.
