It is important investors realize not all exchanges and brokers that offer delivery of the underlying Bitcoin are created equal. Some firms have fallen victim to theft by hackers who have stolen Bitcoin belonging to clients whose money was held at the exchanges. Meanwhile, other Bitcoin exchanges have gone bankrupt (as in the case of Mt. Gox),  as a result of fraud or mismanagement.
I would also encourage you to have a secure place to keep your passwords, maybe written down in a couple of locations or stored in a password manager, just create something which works for you. Also, keep a copy of your private key for each wallet. If you lose your access and lose your keys, then you lose your coins. Don't worry; this is not necessary with every wallet, for example Coinbase and a Nano S will manage your private keys for you, this will all start to make sense once you start.
Realize that Bitcoin isn’t the same as Blockchain. Blockchain technology is something many are bullish on, but that sentiment shouldn’t be confused with being sentiment about Bitcoin specifically. Blockchain is not Bitcoin, a company that calls itself blockchain is not the same as the technology blockchain. The new “blockchain killer” might not be.

Perhaps the deadliest mistake a trader can make is letting emotion get the best of them. Those with the wrong mindset will lose in the long run; Whether it’s losing a trade and trying to get it all back by chasing a phantom opportunity that was never really there, or winning a huge trade just to get too greedy and giving it all right back. Set a clear goal each time you sit down to trade and walk away once you’ve hit your goal. Do the same for loses. Walk away and come back tomorrow. There will be opportunities will be there the next day, I promise.
Needless to say, Bitcoin’s place as an alternative digital asset among cryptocurrencies has become entrenched, despite likely headwinds it will continue to face as it evolves further. The U.S. Securities and Exchange Commission (SEC) announced in early August 2017 that certain Initial Coin Offerings (ICOs) – which use cryptocurrencies for financing – would be regulated as securities.

On cryptocurrency mining: As noted, one way to invest in cryptocurrency is via cryptocurrency mining. That is a valid way to start investing if say you love computer gaming and need a new rig and want to invest in small amounts of cryptocurrency while maybe making back some of the cost of the rig (and maybe even breaking even) but that is an entirely different subject. The average investor will want to trade USD for cryptocurrency on an exchange and avoid the complexities and investments of mining. In all cases, unless you already have a good rig with a great graphics card, you’ll need to put down USD upfront anyway.
This link explains how to use moving average analysis to identify potential opportunities. The short version is that if we see the EMA cross above the SMA and begin shooting upwards, we know that the price is beginning to beat the trend, forcing the trend to change directions. This can make these cross points a good entry point for a trade. Similarly, a good exit point for a trade is usually when the EMA crosses below the SMA.
Coinbase/GDAX will want more personal information than you’ll feel comfortable giving them; there is no way around this. The more information you give them, ID, Bank account, credit card, etc., the higher your limit and the less restricted your account will be. Don’t let this scare you off from becoming a cryptocurrency investor. Every other exchange user went through this process; you have to also. Since you have to trust someone, Coinbase/GDAX is a good bet.
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…
Verification criterion- Since cryptocurrencies aren’t government regulated, trading on exchanges is posed to hacks and misuse of identities. Therefore, all the reliable exchanges will ask you for the verification of your personal identity in one or the other forms to make deposits and withdrawals. To remain on the safer side and avoid money laundering and frauds, you must opt for the step of identity verification while registering on an exchange.

Understanding support and resistance are pretty handy in the trading world, not only with forex, stocks, and commodities but also with the new kid on the block – cryptocurrencies. For example, when prior resistance turns into new support, we often encounter splendid buying opportunities in a strong uptrend. Check this space for a powerful support & resistance cryptocurrency strategy coming soon!
Simply, the OBV is a remarkable technical indicator that can show us if the real money is really buying Bitcoin or quite the contrary they are selling. What we want to see when Bitcoin is failing to break above a resistance level or a swing high and the Ethereum already broke is for the OBV to not only increase in the direction of the trend, but to also move beyond the level it was when Bitcoin was trading previously at this resistance level (see figure below). Here is how to identify the right swing to boost your profit.
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.

Disclaimer: I am not a professional (or even a veteran) trader. I am an intermediate trader with a passion for cryptocurrency. I am disclosing my own ventures in crypto because cryptocurrency trading does make up a chunk of my online income and I want to be 100% transparent with you when it comes to making money online. Investing in cryptocurrencies carries a risk – you may lose some or all of your investment. Always do your own research and draw your own conclusions. Again – this article is aimed purely at advising; draw your own conclusions on whether cryptocurrency trading is right for you.

EDIT: #10 Bonus (Suggested by @kerstenwirth ) — always check the ticker symbol. Ticker symbols are not universal, and may vary from exchange to exchange in rare cases. Those cases, though, can come back to bite you. For example, Bitcoin Cash trades on some exchanges as BCH, while it trades on others as BCC. BCC is also the ticker symbol for BitConnect, which was recently outted as a Ponzi Scheme. If you bought BCC under the impression was Bitcoin Cash, you would’ve lost a lot of money.
