A long-term investment is one where you expect a cryptocurrency to perform better over a longer period of time. Simple! Normally, the minimum time for long-term investment is 6 months to 1 year. Although, some people plan to hold onto their investments for 5-10+ years. It’s up to you how you choose to invest; you can either make your full investment in one go, or you can invest at different times.
For example, if it was thought that things were getting very frothy, and most of the people who were getting in were just gamblers who were buying on credit, then that might be the time to cut loose using that as your signal rather than using a technical one.  On the other side, if you have cryptocurrency that is just hammered to the floor with everyone thinking it’s dead and everyone’s out of it, one can use this opportunity to make a few purchases as a long-term investment and wait for the upturn.
Let’s say on your cryptocurrency chart at 250-minute candles, you see 25 candles where the price stays within a 100 point range. If the price contracted to a daily move of just 20 points, you’d be seriously interested and alert. You should see lots of overlap. This tells you there is a substantial chance the price is going to continue into the trend.
The natural inclination for crypto investors is to identify a new altcoin with the potential for growth, invest heavily when it's still inexpensive to do so, and then reap the rewards when the value increases. That being said, the altcoin market is growing so quickly that many new digital currencies hitting the market might not be good long-term investments.
Bitcoin faced extreme headwinds in March when Alphabet's Google (ticker: GOOG, GOOGL) joined Facebook (FB) in banning ads for cryptocurrencies, which lowered liquidity in the market. In an abrupt reversal, Facebook said on June 26 that it would allow some ads for cryptocurrencies, but continues its ban against initial coin offerings and binary options.
Is a digital asset which is designed to act as a medium of exchange that uses encryption to secure transactions and control the creation of new currency units. Cryptocoins are a subset of digital coins. Bitcoin was created in 2009, thus becoming the first decentralised Cryptocoin. It uses cryptography to secure and verify transactions as well as to control the creation of new units of a particular cryptocurrency.

You could try this instead: You could try to avoid times where you know there’ll be relatively less liquidity in crypto — like nights and weekends — by closing out all of your positions every night and over the weekend. You might also consider maximizing the liquidity to which you have access by trading on a platform that allows you to access many different exchanges at once, rather than trading on only one or two specific exchanges.

Continually doing these things can lead one to gradually cultivate a strategy: a collection of signals that one is good at recognizing and that have a consistent track record. Some traders only buy or sell once they see confluence: multiple signals indicating the same oncoming reversal or trend continuation at the same time. For instance, they might look for candlestick patterns indicating a reversal on both a short-time-interval chart (like a 15-minute chart) and on a long-time-interval chart (like a 4-hour chart).
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.

There are some people who believe that Bitcoin is the only blockchain based protocol which has value and that all others will fail. These people are known as Bitcoin maximalists and their belief is based on economics, specifically Austrian economics, and that the technology which is great for Bitcoin is not useful for anything else. I am more open minded and believe that there are other applications of the technology which will create sustainable ecosystems but I could be proved wrong here. It is important to spend time doing your own research and building up your own view on where the technology may be used.
This is probably the most important factor to look at when deciding whether a cryptocurrency will survive into the future or not. Some cryptocurrencies, apart from acting as coins and trading assets, also provide platforms, serve as the fastest means to move money across the globe, try to solve a certain problem in society or in the cryptocurrency ecosystem, and do a lot more.

You could try this instead: Develop your own day trading strategy with indicators and rules that you understand and hold yourself to. Then read the news, but read it with a grain of salt — and try not to make trading decisions based on rumors that might be debunked the very next day. You shouldn’t buy just because you see the price rise and fear missing out.
OmiseGO (OMG) is a public financial technology that’s based on Ethereum. The concept of OMG is to enable peer-to-peer value exchange and payment service in real time across not only decentralized currencies but fiat money as well. OmiseGO allows anyone on its network to process financial transactions (payrolls, B2B, remittances, payments, etc.) in a much more inexpensive and decentralized manner.
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!

In the beginning when I was shooting for 20% gains on a trade and not knowing what to look for, I worked a lot more. Not only that but I also let my emotions control my trades. For example, I once purchased Stratis after the price dropped massively. My assumption was that on such a sharp decrease in price, it had to rebound eventually. I was wrong. The price kept diving. I had to hold the currency for 2 weeks just to secure a 35% loss instead of an 85% loss. I was constantly tuned into that chart waiting for an opportunity to sell back to Bitcoin.
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.
Always pay attention to Bitcoin. Most altcoins (every cryptocurrency except Bitcoin) are pegged more closely to Bitcoin than Asian currencies were to the USD during the Asian Financial Crisis. If Bitcoin price pump drastically, altcoins price can go down as people try to exit altcoins to ride the BTC profits; inversely, if Bitcoin prices dump drastically, altcoin prices can go down, too, as people exit altcoins to exchange back into fiat. The best times for altcoin growth appear when Bitcoin shows organic growth or decline, or remains stagnant in price.
