It is important investors realize not all exchanges and brokers that offer delivery of the underlying Bitcoin are created equal. Some firms have fallen victim to theft by hackers who have stolen Bitcoin belonging to clients whose money was held at the exchanges. Meanwhile, other Bitcoin exchanges have gone bankrupt (as in the case of Mt. Gox),  as a result of fraud or mismanagement.
These are what allow us to buy and sell cryptocurrencies. There are a handful of popular crypto exchanges, some of them have advantages over others. For example, some exchanges don’t allow us to deposit and withdraw using fiat currency like the U.S. dollar and euro; others aren’t available in certain countries. In this guide we will focus on two very popular exchanges, GDAX and Poloniex. GDAX gives us the ability to use our fiat currency to buy Bitcoin. Poloniex does not, but does give us a wide array of altcoins to trade. There, we’ll be using major coins like Bitcoin and Ethereum to buy the altcoins, and vice versa. Other popular exchanges such as Kraken and Bittrex offer even more coins.

One of the most powerful tools made available by the Blockfolio app is the price tracking functionality it offers. The Blockfolio app is able to deliver running price updates via push notifications directly to a smartphone as soon as a currency reaches a predetermined level, increasing reaction speed for high priority buying and selling actions when prices reach a specific threshold.
In contrast to Forex or stock markets, crypto industry have much more risks for traders and investors including scam exchanges, hacker attacks, delisting of tokens and the others. Cryptocurrency market is volatile and coins have no underlying value meaning they may cost either $100,000 or $0 depending on demand and supply. Nobody can predict today the price of Bitcoin for several years.
You cannot “buy the dips” if you have all your money to invest already invested. LET US STRESS THIS POINT! The point should be obvious, but it bears repeating over and over. It is tempting to go all-in, but that limits your options. Consider always having some funds to the side to buy an unforeseen downturn. Even if you want to “go all-in” on crypto… leave yourself at least a little money to the side just in case. If you are all-in and the price takes a hard downturn, it takes lots of options off the table. It is hard not to go all-in when a coin goes down 60% – 80% over the course of weeks or months, but sometimes they go down even more than that, and it is wise to always prepare for the worst case.

Accept that coins can go to zero, and even good coins can lose up to 80% of their value (especially against BTC). There are many coins that didn’t make it to 2018 that were once highly valued and popular. Meanwhile, even some giants of today like ETH and XRP have seen their value in BTC prices drop to depressing levels. You should prepare for this mentally and have a strategy that factors this in. If you buy the dip in ETH from .15 down, .08 may look like an excellent price, but you have to be ready for .02. ETH holders who didn’t prepare for this had a depressing June 2017 – December 2017. Heed my warning, that new coin doesn’t have to moon twice, it can go to literal zero, and even those that will moon again… they can have long seasons of stagnation in between (where they lose value against BTC for months on end). See the Crypto Graveyard and please look at the historic charts of major alts like XRP (the gap between moons is real and some coins really don’t make it).

Don’t invest blindy. There are people in this world who would sell a blind person a pair of glasses if they could make money. Those same people play in the cryptocurrency markets and use every opportunity to exploit less-informed investors. They’ll tell you what to buy or claim certain coins will moon, just to increase the prices so they can exit. Due to the highly speculative nature of the cryptocurrency markets today, a good investor will always do his or her own research in order to take full responsibility for the potential investment outcome. Information coming from even the best investor is, at best, great information, but never a promise, so you can still get burned.
