Analyst Willy Woo, based on the historical adoption curve of Bitcoin, explained when Bitcoin could develop enough to rival the US dollar (USD). Woo stated that the financial world now sees Bitcoin as a rapidly rising asset class. However, the current total market value of this currency is only about 1.2 trillion USD, and analysts point out that the value of an asset class is usually measured in tens of trillions of dollars. Woo believes that such expectations for BTC mean that the financial world believes three things: BTC will grow at least tenfold from now on (breaking through the major milestone of 10 trillion USD in market value), be comparable to USD in scale, and become a reserve asset. Woo referred to cryptocurrency's "adoption" curve; it can be seen from charts that according to analyst model estimates, Bitcoin's user number currently equates to approximately 4.7% of global population. If it continues along with internet’s S-curve trend, BTC might still be in its early stages. Assuming this is indeed true, token users will start accelerating growth from now on. Woo thinks this situation would occur when curves enter between 25% and 40%, which may happen during the 2030s.
