Early cryptocurrency supporters, former Olympic competitors, and founders of the cryptocurrency exchange Gemini, Cameron and Tyler Winklevoss took to the popular content aggregation platform Reddit to conduct an AMA.

An “AMA” on Reddit, stands for “Ask Me Anything” and gives notable individuals, or in this case, twins, a soapbox to answer the burning questions the Reddit community may have. In the AMA, the Winklevoss twins touched on some personal subjects, but overall kept the discussion focused on the cryptocurrency sector.

In the Reddit thread dedicated to the Q&A session, Cameron and Tyler Winklevoss reasserted their commitment to pursing a Bitcoin ETF, and made some comments about the future of Bitcoin. Tyler noted that the twins believe that “bitcoin is better at being gold than gold” itself, and will eventually surpass gold’s market cap of $7 trillion.

Bitcoin’s current market capitalization currently hovers at around $70 billion. Should Bitcoin reach the $7 trillion market cap the Winklevoss twins hope, each of the 21 million bitcoins in that’ll ever circulate will be valued at roughly $333,000 per BTC.

Bitcoin draws its comparisons to digital gold due to the scarcity of the leading cryptocurrency, as was designed by the mysterious Satoshi Nakamoto. However, Bitcoin existing digitally gives it a number of benefits over gold, which has long been used as a hedge during times of economic distress.

For Bitcoin to reach such a price and market cap, it will need to be widely adopted by the public. The Winklevoss twins suggest that will occur when money works the same way as email does, and is available to send instantly, any day of the week, 365 days a year. The comparison of money to email does a great job showing just how archaic the current monetary system is compared to the rest of the developing world.
