As well as buying crypto using fiat currency, a centralized exchange is somewhere you can store funds and exchange the likes of Bitcoin for other coins and tokens. Examples include Coinbase, Kraken and Binance. Although there is less risk that your funds will disappear if you forget a password or your private key, it’s important to go with reputable providers who have high security standards. That’s because there have been cases where millions of dollars have disappeared from these exchanges overnight through hacking.
The trading strategy used is bollinger bands. (You can create bollinger bands on graphs in poloniex). The strategy is to buy when price touches lower bollinger band and sell when the price is above your bought price and also hits high bollinger band. If the price goes down and again touches lower bollinger band then invest another 25% of total investment assigned for a currency.
We will describe these cryptocurrency trading strategies for you here, and the first ones we’ll review are the technical strategies.  With technical trading, you have two basic strategies to use for the trading of cryptocurrency.  You’re either going to trade with the trend/momentum of the current market, or you’ll be trading for mean reversion.  Mean reversion is when you think the spring has been pulled too tight, and your waiting for that spring to snap back to an equilibrium point.
On top of the possibility of complicated reporting procedures, new regulations can also impact your tax obligations. The U.S, the ‘property’ ruling means your earnings will now be deemed as capital gains tax (15%), instead of normal income tax (up to 25%). Each countries cryptocurrency tax requirements are different, and many will change as they adapt to the evolving market. Before you start trading, do your homework and find out what type of tax you’ll pay and how much.
Arbitrage trading can be described as the simultaneous purchase and sale of an asset in order to profit from discrepancies in its price. In other words, arbitrage traders will purchase an asset in one market, and then sell that same asset at a higher price in another market. In the context of the cryptocurrency market, arbitrage trading might resemble something like this:
Know when to take a loss. Nothing is less fun than taking a loss, but if you are going short in BTC and you haven’t set a stop, sometimes it makes more sense to take a loss and wait for a better price than it does to suddenly start going long. The best way to know when to hold ’em and or fold ’em is some basic TA on longer term charts (I will use things like MACD on 6hr – 12hr – 1 day candles to confirm trends) paired with unwavering discipline.

Ethereum ETH, Monero XMR, Factom FCT, DASH, are all leading coins and traded the most volume daily. You should follow the coin’s chart and identify low and stable periods. Such periods are likely to be a consolidation period by the whales, and when the right time comes, accompanied by a good press release of the project, the pump will start and they will sell in profit.
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.
Suppose you’re watching BTC’s chart and notice multiple Doji candlesticks, a classic indicator of indecision in the market. You have a feeling from a few other indicators that the price is about to rise, so you buy more Bitcoin — but alas, the indecision swings the other way, and you’ve lost money (but hopefully not that much, since you’re placing stop-loss orders!).
You might be familiar with traditional investment funds. These are pools of investor capital managed by a team of professional investors. These specialists use a range of strategies, including the ones we’ve talked about, to earn returns on all of the capital within the fund. Investors in the pool benefit from having access to the skills of the professional traders, while the traders benefit from having much more capital to trade with. It’s a win-win.
Another very common mistake beginners make is spending all their trading money in one go. If you find a good entry, you should buy in with a percentage of your funds (50% - 60%) and hold the rest to see whether your entry works. This way, even if a coin drops following your purchase, you can average it down by buying more at the dip. Similarly, if the uptrend continues, you can always buy more, and even though this approach reduces your profit margins, it secures your position and prevents you from being all-in on a trade that goes south.
Take this into account when holding Alts for the medium and long term, and of course choose them carefully. What kind of Alts are recommended for the long term? Remember, this is only when there is a reason for making a trade. The projects/coins that have a higher daily trading volume and which have a widespread community behind them, with continuous development, are here to stay with us:
Similar to investing, diversification is king. To lower possible trading risks, it’s better to distribute your money into different cryptocurrencies. While some grow, some will fall and by not putting all your money on single bet you can balance the losses. That said, trading requires research and tracking changes and there are a lot of cryptocurrencies — which means a lot of research. Start with a few and expand slowly.
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.

To perform cryptocurrency arbitrage, you need to find an opportunity where you can buy a cryptocurrency for less than you can sell it on another exchange (minus the fees and commission). Once you’ve found one, all you need to do is simultaneously buy Bitcoin on the lower-priced exchange and sell on the higher-priced one. It’s easy to make hundreds or even thousands of dollars in just a few seconds if you have enough funds.

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).
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.
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.
