This article is a very high level introduction to the Grayscale Bitcoin Investment Trust (OTCQX:GBTC). If you are unsure about what Bitcoin (BTC-USD) is, then you can start by reading some of my articles on the subject. Alternatively, if you're a visual learner there are many great videos that can get you up to a basic level of understanding. Let's begin.

As a general rule, what goes up can come down, and what goes up particularly quickly is privy to come down just as quickly. This is not to say that things will come down if they go up, but merely that they can, and certainly have before. This is particularly noteworthy today, with ethereum having seen some truly wild gains this year, all the way up from $7 back in December of last year to over $350 presently — a gain of 50X in just about half a year. Again, this isn’t to say ethereum will fall, but merely that it very well might, for any host of reasons, and it’s very important to keep this fact in mind and not overextend yourself with investments you perceive to be less volatile than they truly are. I’ll get back to this more later.
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.
Coinbase Pro expands on these basic capabilities. Coinbase Pro offers options to make market orders, limit orders and stop orders, to buy and sell. Instead of trading exclusively from USD to a given crypto, Coinbase Pro allows users to trade between cryptocurrencies (so, selling Ethereum for Bitcoin, for instance), and in different currencies (USD, EUR, GBP). Like Coinbase, the cryptocurrencies available for trading on Coinbase Pro are Bitcoin, Bitcoin Cash, Litecoin and Ether.

Bitcoin is a digital currency, also known as a cryptocurrency, and is created or mined when people solve complex math puzzles online. These bitcoins are then stored in a digital wallet that exists on the cloud or the user’s computer. Because bitcoins are not housed in bank accounts, brokerage, or futures accounts, they are not insured by the FDIC or SIPC.
