You do not need to right away choose the first exchange option you see on Google search. Take your time to research as different crypto exchange platforms available in the market vary from each other in terms of functionality and style of trading they offer. To save your time, I’ve listed below the different types of cryptocurrency exchange platforms that’ll help you get a better idea:
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.
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.
Bull markets, bear markets, corrections, and bot manipulations.  All part of the cryptocurrency trading world that has gotten people so interested in trading crypto and being part of the game that’s sure to change the investing world forever.  These new markets are right now looking for new investors, but how to invest if you are a beginner?  Here are some cryptocurrency trading strategy tips.

The smart selection of assets ensures the fund avoids the biggest pitfalls of the industry. Only assets with excellent fundamentals and growth potential pass the strict filtering process. Continuous review minimizes the exposure to bad assets. The portfolio is diversified across the whole blockchain industry, with different cryptocurrencies, technologies, industries, fiat currencies, and traditional assets all represented. The cryptocurrency market runs 24/7, and PentaFund ensures that the funds are protected at all times.

Take profits. Some investors think “taking profits” is a dirty phrase, but it is a rather conservative strategy none-the-less. Taking profits can result in you making less money than you would have if you did nothing and just “let it ride”… but that is only true if Bitcoin goes up over the long term. If you have hefty profits, consider taking them off the table, and then waiting for a lower price in the future. Worst case, you can buy back in at a higher price later (leaving some potential profits on the table). TIP: If a coin just went up 400%… consider taking some profits. Cryptocurrency almost always corrects at some point after a big run. I personally would say HODLing after making 400% gains is called GREED. I won’t ever sell my full stack in one chunk, but I’m going to start averaging out when the MACD turns bearish after a 400% – 1,000% run if the run was somewhat organic. If the run was the result of a pump and dump, then I will likely take it all off the table quickly. Pump and dumps are frustrating events, like I said, watch out for manipulation.
We've had splits in the technical community before. Two years ago, Angular was the dominant Javascript framework and React was new with a small following. Angular's community split between Angular 1 and 2. Today, there are 236,472 repo's associated with React compared 247,335 for both angular variants. Alone, interest in react is about to supercede both variants of Angular combined.
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 :)

It is important not to neglect the power of altcoins, or non-bitcoin cryptocurrencies. Altcoins are less prone to public speculation. Their smaller market caps are more prone to larger swings in pricing. Each altcoin has a purpose and an intent, catering to different niches. There are larger risks associated with investing in altcoins, but also larger rewards. Our personal favorites are DASH, ZCash and Monero.
To stress some points made above, realize that a diverse portfolio and investment strategy will eat into gains as often as it staves off losses. The only way to make big profits most of the time is to make risky moves. If you go all in on a single coin at a given price and it goes up, that is a payday. If it goes down, your investable funds are locked into that crypto (unless you want to sell at a loss). Diverse strategies protect against this, but they will also eat into your potential gains (as it is rare for everything to go up or down at once). Know what you are looking for and know how to weight your portfolio to reflect that.
Bitcoin (BTC) is King/Queen; Don’t Get Overly Optimistic About Altcoins. Those who invest in BTC tend to get itchy fingers when BTC stagnates and alts go up. Sure, going into IOTA or ZCash can be a brilliant move at times… at other times you’ll be holding the bag while everyone moves back into BTC. Stick with coins you know and like, but consider always being partly in BTC (not 24/7, but in general). This advise applies somewhat to Ethereum as well, but first and foremost BTC is the center of the crypto economy.
Don’t FOMO. This is a spot that people most frequently lose money on. A dash of manipulation, two tablespoons of media hype, a cup of CME and CBOE announcements, and a generous handful of FOMO drove Bitcoin prices from $10,000 to $20,000 in December. Since that time, Bitcoin fell to a low of $9,000 and is currently sitting at around $11,000. It’s easy to look back and say, “if only I waited one month, then I could’ve bought at $9,000 instead of waiting for Bitcoin to hit $20,000 again for me to break even.” But the reality is, the combination of 1) being greedy, 2) investing blindly, and 3) FOMO were likely large contributors to the purchase at an all-time-high. Even in the crazy world of cryptocurrency, if a coin pumps that quickly, it will correct — it’s a matter of time. Speculative pumps are almost always followed by dips. While trying to jump onto a train going full speed sounds like something straight out of a James Bond movie, I’m sure most of us can agree we would probably save some limbs if we just waited for it at the next stop.
