The screenshot below is a basic representation of these concepts, where the horizontal lines roughly mark zones where price either finds a ceiling or a floor, and generally, in an uptrend, past resistance zones can become supports later on (notice how candles earlier failed to breach the second-last horizontal line, but later bounce off from the same) and in downtrends, support zones can become resistance.
How often will you buy or sell? Some people want to be day traders, but we’ve shown that holding could be the best bet. The general rule of thumb is that the longer of a time horizon you plan on holding for the less risk you incur. This rule carries over into the realm of cryptocurrency from stock investing. However, here may be times to simply cut and run. Declines due to unforeseen structural issues are an indicator to cut losses and sell out.
Learn to value coins in BTC. Ether aside, Bitcoin is the current primary currency of the crypto economy (i.e., its what you have to use to buy most altcoins). Those new to crypto tend to value things in dollars. Meanwhile, even seasoned cash traders value coins in dollars. However, enough crypto traders will value coins in BTC for it to matter. If you aren’t aware of the BTC charts, you won’t be able to properly understand the trends everyone else is analyzing and reacting to. You don’t have to make getting more BTC your goal, but you must have the BTC prices of altcoins on your radar. There are times when all coins move up, but altcoins steadily lose value against Bitcoin. Those who know will be the first to dump altcoins for Bitcoin; this will set off a vicious cycle that can result in the stagnation of altcoin prices.
So let’s take our hypothetical 1 BTC from before and take a short position on Ethereum. We are able to borrow 2.5 BTC worth of ETH and sell it. 30 minutes later, the price of ETH has plummeted 10%. Now we can close our short position, buying back 2.5 BTC worth of ETH; except now, since the price has dropped, we are buying more ETH than what we sold. Our borrowed coin can be payed back and we take the rest as profit!
Now that you’re well-versed about the types of crypto exchange platforms available in the markets, you might think it’s time for you to get started with the investments. Not yet though! Like stock exchange and money trading, crypto trading is not a piece of cake. You need to learn the basics, gather all the necessary information, and get prepared before ultimately heading towards investments. Here’s a list of things to check before finalising an exchange:
Bitcoin is different than any currency you’ve used before, so it’s very important to understand some key points. You can use them to send or receive any amount of money, with anyone, anywhere in the world, at very low cost. Bitcoin payments are impossible to block, and bitcoin wallets can’t be frozen. Actually, the Bitcoin network is unstoppable and un-censorable.
Ideally, a rookie trader should start by choosing a reliable exchange and playing with popular coins, such as Bitcoin or Ethereum. However, the learning by doing approach is too slow for those who want to succeed fast. Joining a community of like-minded traders could be one of the best decisions to make: there are plenty of groups on Telegram or regular meetups in the US and other countries.
Since all of the virtual currencies remain a speculative asset, investors should avoid buying them for their retirement portfolios, says Jason Spatafora, co-founder of Marijuanastocks.com and a Miami-based trader and investor. Cryptocurrencies made up less than 2 percent of his portfolio a few months ago, but he is no longer trading them because of the extreme volatility.
Blockfolio also provides complex and powerful analytical and charting tools that make the tracking price trends of the currencies you’re investing in seamless and practical. The app can also be programmed to gather together the latest news stories from your favorite cryptocurrency news websites and sources and present them in a comprehensive array.

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.
