Watch out for scams. There are a few different scams in the crypto world. Anything that isn’t buying a coin with a good reputation is a big risk. Learn more about scams. In short, be super careful about anything that promises free coins, sick returns, or wants you to lend your coins. Buy the top coins using a careful strategy and ignore all the sites promising you they can outperform the market if only you give them X, Y, and Z.
I’ve met so many people that are speculating in crypto these days that have never even read Satoshi’s white paper on Bitcoin. Not only are they not practitioners (tech experts), they even are too lazy or too blinded by greed to even do a baseline level of work. There are many easy ways to quickly get up to speed on crypto and educate oneself you just have to do the work (one of my go-to resources is a company called Oddup which is an ICO/Crypto rating company used by all the major crypto hedge funds and institutional players).
On the other hand, some coins serve a very unique function in the real world. For example, Power Ledger is a fairly new and interesting cryptocurrency. The goal of this project is to provide a system for consumers to trade electricity with one another. For a young project such as this, the best thing you can do is first decide whether you believe in the technology and the team behind it. The second thing you can do is read news surrounding the project. All of that information, along with a look at the coin’s market cap, is going to ultimately determine whether you think the technology might reach mainstream adoption, thus making an investment worth your while.

Bitcoin (BTC) has been engaged in a predictable up and down pattern where it absolutely crashes at the beginning of any year and then sky-rockets as the year nears its end. Bitcoin held steady at around $19,000 in December 2017, and then sure enough – crashed big time to around $6,000 at the beginning of 2018. At the time of writing, March 8th 2018, the price of Bitcoin is relatively stable between $10,000 and $12,000. In my opinion, the price will run again soon.

Ethereum'is on the trouble! Almost all the altcoins trades above the major counter-trendline but Ethereum'is not on the list anymore. It has a break downwards from the trendline and from the strong area which is not the good sign but we can find something positive also, currently, it has an opportunity to make a new higher low on the market structure and it shows ...
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.
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.
