A “manageable amount” is obviously subjective and will vary for each person based on things such as time available to dedicate to trading. Feel free to do your own research to find the right exchange for you. I tend to value user experience of an exchange over the amount of coins on it. Ultimately, what exchanges you use is going to depend on your own personal preferences. GDAX and Poloniex will provide sufficient resources needed to be a successful trader, so they are definitely a good place to start.
Figure out if you want to go long or short. Are you going short with every penny you have to invest, or are you going to go long with some and short with some? Long-term investors will pay a lower tax rate if they can hold for over 12 months, but as a trade-off, they WILL have to sit through corrections (likely seeing their balance go down 50% plus on paper as often as they see it go up). Short-term investors can avoid corrections if they are nimble, but they’ll owe taxes on the profits from each trade they do along the way (see: how taxes work with cryptocurrency to understand how the long term and short term capital gains tax work with cryptocurrency).
I have been following the crypto markets since mid 2017, just in time to witness the incredible surge of the digital asset industry. Fascinated by the potential of blockchain technology I’ve started to dig deeper and that’s how I ended up meeting the Toshi Times team. I hold a Political Science degree, therefore the crypto regulation development is particularly interesting for me. I’m also heavily involved with music, running my own label, a YouTube channel and working with distribution. People call blockchain the ‘Fourth Industrial Revolution’ and I believe it will change our daily lives in the coming years and we will have the front row seats to witness it.
On April 12th, 2018, Bitcoin’s (BTC) price jumped over 10% in a single minute. If you’d been properly positioned with a good strategy, you could have made a single trade and increased your position’s value by 10% almost instantly. On the other hand, if you were shooting in the dark and didn’t have a strategy, you could have taken a big hit in 60 seconds.

AvaTrade offers phone support and allows deposits and withdrawals through multiple avenues such as credit/debit card, wire transfer, e-payments, etc. The firm claims one-click functionality for buying Bitcoin or Bitcoin cash on its MT4 platform. Meanwhile, Plus500 does not have phone support, and instead, services clients through live chat and e-mail. Markets.com assists through in-platform live support and 24/5 help center.

 Major Altcoins have the most volume traded again the USD. Thus, analyzing graphs of those Altcoins should be done whilst comparing them to their Bitcoin graph and their dollar value graph. Here on CryptoPotato we make sure we do that for our weekly market reports. If we were solely analyzing the Bitcoin value chart, we would surely miss the accumulation period of Ethereum by roughly $300 (recall $300 of Bitcoin accumulation back in 2015?). At the time of writing Ethereum is trading a month later, for more than $1000 for one Ether.
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.

So how do you know if you should invest in an ICO? It’s not about science, it is important to pay attention to the level of seriousness of the project and its team. Look for the project’s website (does it look like a child has built it during computer school?), Who is the team behind the project – Are they hiding behind nicknames or proudly present themselves on their website? Pay attention to the Bitcointalk thread (does it exist at all?) and how the team members respond to technical questions. Is there a large community behind the project? Expect to see a Slack gathering its community. Watch out the amount raised: A project which had raised too little will probably will not be able to develop over time, a project which had raised huge amount – there won’t be enough investors left out there to buy coins on exchanges. And most importantly is risk management. Never put all eggs in one basket and invest too much of your portfolio in one ICO.
Bittrex is a US based crypto exchange platform that allows you to trade in large numbers of trading pairs. You’ll also be able to get all the major cryptocurrencies on the platform including litecoin, darkcoin, and nextcoin. Along with this, it also offers Ethereum and Neucoin. If you are looking for a platform that offers reliable security, then Bittrex is the right choice for you as it offers 2FA and is well-regulated and compliant with the rules of the United States.
I have been using Coindex for a long time now and am constantly impressed by the time and care Josh and Cellaflora put into the project. There is an emphasis on perfection and testing the app's features before release and this has amounted to a polished and irreplaceable part of my iPhone. Coindex will always have a space on my dock and can't wait to see what they add next :)
Let’s say on January 2, 2017, you owned $1,000 and exchanged it into euros (EUR) with another market trader at a rate of EUR€0.9565, leaving you with EUR€956.50. Then, on November 24, 2017, the value of the US dollar had fallen from EUR€0.9565 to EUR€0.8380, so you decide to exchange your euros back into US dollars. After finding someone willing to sell their US dollars for your euros, you carry out the exchange at the new price. Your EUR€956.50 is now worth $1,141.40, leaving you with a profit of a little more than 14%.
So you can identify cryptocurrencies that will survive into the future yourself. The market is damn volatile and when you allow suggestions, everybody is marketing their own cryptocurrency everywhere, so you end up getting what many people use but not what might truly survive in the long term. So make your own decision by knowing what makes a cryptocurrency survive for long.

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.
