If you’re not quite ready to dive into cryptocurrency, there are some related investments to consider. For example, some Exchange Traded Funds (ETFs) offer “ways to play” in the crypto market, but do not directly hold cryptocurrency or its derivatives. In general, these ETFs hold stock in companies with exposure to or involvement in processes that interact with or support crypto markets by participating in mining or simply top cryptos to buy right now by holding large balance-sheet positions in cryptocurrency. These investments allow you to dabble in this emerging landscape without taking the cryptocurrency plunge. Specifically, blockchain solves the "double-spending problem" associated with digital cash. Since digital information is easily copied, digital money requires a mechanism that reliably prevents a currency unit from being "duplicated" or otherwise spent more than once.
