If you can figure it out, use MACD (the divergence and convergence of moving averages) to help you understand if we are in a bull or bear market, and to help you understand why the price just dipped or shot up. Other indicators are very useful, but MACD is particularly useful for the tactic being discussed because it gives you a quick visual of the current trend.
If you understand the difference between leveraged and non-leveraged positions, so you could choose between them. (Also, bear in mind not all broker platforms offer leveraged trade.) Leverage means you only have a small percentage of what you invest or trade. You can own $50 out of $1,000, with the rest borrowed from a broker. In its turn, the broker works on several risk levels, offering higher returns for higher risk. However, you yourself do not own the underlying asset; the broker does.
NOTE: The image below shows daily candles on a 1 year BTC chart. When the short term 12 day exponential moving average crossed under the longer term 26 day in January 2018, it pretty clearly marked the start of a bear market in retrospect (a true correction, not just “a dip”). You can see that buying the dip and holding in this time was not ideal (not the worst move perhaps long term, and not a bad move for short term trades, just not ideal for a buy and hold strategy as far as we know so far). That overarching bear market is an example of a market in which one has to apply a bit more nuance to their “buy the dips” strategy.

In general, bigger market cap coins are less risky but have a lower chance of phenomenal returns. On the other hand, lower market cap coins generally have much more risk attached, but sometimes have the potential for greater gains. In cryptocurrency you must be aware that a large market cap coin can still potentially lose 70% or even 100% of it’s value.
Other coins might embrace niche aspects such as entertainment, bill paying, security, and other aspects of decentralization. For example, consider DentaCoin that is the dental world’s first cryptocurrency enhancement. This coin does not vow to be the next Bitcoin; it simply wants to be widely used in the world of dentistry. The coin Ripple wants to be used by banks opposed to competing against them. The coin SunContract eliminates the middleman between providing and purchasing solar energy, which increases what homeowners earn from their solar panels. These kind of niche applications allow various industries to take advantage of the powers of cryptocurrency in very specific areas.

Here’s what’s Lisk all about: Most developers today rely on centralized giants, such as Google Play and the AppStore to put up their newly developed apps. These giants take much of the profits and attention from these apps, and Lisk believes all this should be going to the developers themselves. This is where its Javascript-based tech comes in. Lisk is incredibly exciting because it aims to offer a decentralized apps platform, one that actually favors the developers, and therefore gives them the bigger piece of the cake. Lisk was previously Crypti, and after proving itself on a community level, it was forked by Max Kordek and Oliver Beddows into Lisk, in 2016.
Oh boy.... Let me channel Mr. Miyagi: "walk on right side of road, fine. Walk on left side of road, fine. Walk in middle of road, splat!" This interview was middle of road, with nothing we haven't heard a dozen times already, offering frankly very little for crypto 'newbies' or crypto 'veterans', or even those who think crypto is crap. Just a big tub of vanilla ice cream, with no actionable questions or information in any of those directions. This could have been on the 'Today' show.
But here, more than anywhere else, is where you need to proceed with caution. Bitcoin is already incredibly risky, imagine what risks smaller and lesser-known crypto brings. Rounding out a portfolio with other cryptocurrencies may be able to help you evaluate the state and perhaps the future of that market, but many of them can quickly prove to be a flash in the pan. The sudden rise of initial coin offerings -- a method of crowdfunding new cryptocurrencies in a way that avoids venture capital entirely -- has many people excited for the future, but also has many wondering if it's going to create an even more dangerous bitcoin bubble.

This is just my 0.02$, as always, I can be completely wrong, and I maintain the right to contradict myself in the future. Also, for the record, this article references only my opinion and is for information purposes only. It is not intended to be investment advice. Seek a duly licensed professional for investment advice if you want to. And, remember, always do your own research (DYOR).
There are so many hoops to jump through to set up for mining and each coin has its quirks. The power of your machine and graphix card and your power consumption are all important. My friend mined for 8month Eth and only made couple of hundred bucks by time you subtract power useage etc. He already had a powerful machine used in film industry for video graphix just sitting around so he thought he’d put it to use over that time for a laugh and see what happened. It took many hours messing around to set up and occassionally nursing it over that period. Of course he had to use his machine also occassionally which compromised the performance.

Investors in any Vehicle must have the financial ability, sophistication, experience and willingness to bear the risks of an investment in that Vehicle. Any offering or solicitation will be made only to certain qualified investors who are “accredited investors” as defined under Regulation D of the Securities Act of 1933 (the “Securities Act”). Qualified investors may only invest in a Vehicle pursuant to documentation made available by Grayscale, which should be read in its entirety. Information provided about a Vehicle is not intended to be, nor should it be construed or used as, investment, tax or legal advice, an investment recommendation, or an offer to sell, or a solicitation of an offer to buy, shares in any Vehicle. Any offer to sell or solicitation of an offer to buy shares in any Vehicle is made only by delivery to qualified investors of the offering documents for that Vehicle (the “Offering Documents”), which contain material information not available on this website and which, in the event of conflict, supersede any information available on this website in its entirety. In making an investment decision, investors must rely on their own examination of the applicable Vehicle and the terms of the offering contemplated by the applicable Offering Documents, including the risks involved.
On the flip side, if the world suffers a global financial meltdown on the scale of the Great Depression or something similar again, and fiat currencies start to crater, it very well may be such that governments are forced to resort to accepting bitcoin and other cryptocurrencies, if enough people simply flat out refuse to put their stock in fiat. This was exactly what the US government was forced to do just 13 years into their original experiment with Continental currency, when they agreed to promise to back all the currency they issued with hard gold and silver.
Virtual currencies, including bitcoin, experience significant price volatility. Fluctuations in the underlying virtual currency's value between the time you place a trade for a virtual currency futures contract and the time you attempt to liquidate it will affect the value of your futures contract and the potential profit and losses related to it. Investors must be very cautious and monitor any investment that they make.
