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.

For instance, you might have a day trading strategy that exploits differentials in tightly correlated cryptocurrencies: BTC and ETH, for example. If you think that BTC and ETH are tightly correlated and you see that ETH is disproportionately low, you might buy ETH with the expectation that ETH will rise up again to restore its typical relationship with BTC. However, this might be a case of contagion: the whole market is going down. In this case, your technical analysis could be your downfall: you’ve just bought into a position that’s still going down.

All of those statements are false. I live in the US. I have the Binance app (there is a very simple tutorial on the couple of extra clicks required for ios, if you click on the link in the post above. And Tab Trader works just fine in the US as well if you set it up properly. There are tons of tutorials and videos that will walk you through it. If you aren’t willing to put in the time and effort to figure it out, that’s fine. But just because you can’t figure it out, doesn’t mean it doesn’t work just fine.
This analysis can be done by searching for information on the number of transactions performed per day and the investments that banks or financial institutions have made in Bitcoin companies. In addition, information on the growth of companies of Bitcoin and blockchain can indicate a possible growth of cryptocurrency, as well as new use cases such as international payments and payment processors.
There are a number of tools you can use to maximize profits and minimize risks, such as margin trading, leverage, and stop-loss orders. Shorting Bitcoin and other cryptocurrencies can be done in a variety of ways. Just looking at the Bitcoin price chart for early 2018, you can see that those that spotted the downward trend in mid January and made a short trade would have made 40% profits by exiting one month later.
The next thing we’ll need to do is deposit fiat currency into our account. The easiest way to do this is by adding a bank account. Once you’ve initiated the deposit, it will take 4 business days to appear in your account. Kind of a bummer, I know; but the idea is to only need to do this once, as we’ll be growing this initial investment day by day with our trades.
When buying coins, and especially with Bitcoin, you will notice that your purchase is in decimal. A Bitcoin itself is relatively expensive, around $10,000 at the moment (as of 15th Feb '18). If you were to purchase say $5,000 of Bitcoin, you would at today's rate be purchasing around 0.5 of Bitcoin. Do not ever worry about this; Bitcoin operates at eight decimals places. You do not need to own a whole Bitcoin or any coin for that matter. Consider it like pence in the pound or cents in the dollar, but with more decimal places.
Only invest what you can lose. During the recent crash in January 2018, hobby-investors got burned. Reports of frustration and losses came at the cost of broken monitors, smashed laptops, and heavy monetary losses. While the rules are in more particular order of importance, it’s safe to assume that this is the most important rule, the rule to rule the rules. As soon as your money is converted into cryptocurrency, consider it lost forever. There is absolutely no guarantee you can get it back. Losses don’t simply come from dips in the market; extraordinary factors such as hacks, bugs, and government regulation can mean you’ll never see any of your money again. If you are investing money you can’t afford to lose, you need to take a step back and re-evaluate your current financial situation, because what you’re about to do is an act of desperation. This includes: using credit cards, taking out mortgages, applying for loans, or selling everything and traveling the world (as glamorous as that sounds).
