While determining how good any investment will be is ultimately a guessing game, there are some tried and true ways to determine an assets worth. One of the simplest ways to think about bitcoin as an investment is to consider its rise against the U.S. dollar. Recently, bitcoin prices eclipsed $8,000 and have reached beyond $10,000. If you had invested in the digital currency when its worth was still hovering around $800 just a few years ago, or when it was first introduced in 2009 and worth nothing against the dollar, you would probably be convinced that it made for a good investment.
Furthermore, an underpinning concept behind Bitcoin is that there will only ever be 21,000,000 tokens, meaning that it may stay consistently valuable or increase in value relative to other types of currency which can be printed endlessly. Other reasons that the asset seems like a good investment include its growing popularity, network effects, security, immutability and status as the first ever in a growing world of digital currencies.
