Cryptocurrency market participants are predicting a fall in the number of digital currencies in circulation this year as the projects behind them fail to gain traction or consolidate.
2017 saw a boom in so-called "initial coin offerings" (ICOs), where startups issue their own digital currencies — structured like bitcoin — in exchange for real money to build their businesses.
Startups raised over $5 billion through ICOs last year and there are now over 1,400 cryptocurrencies in circulation. These coins can be traded on online exchanges, unlike equity in early stage, private businesses.
Regulators around the world have warned that these investments are highly speculative andinvestors risk losing all their money.
