The US is 4% of the world population, but something like 20% of the GDP, and probably about 60% of the GDP that can be devoted to frivolous things like investing in Bitcoin (e.g. expendable income).
You're forgetting Europe, Japan, South Korea, and the growing middle classes in India and China? Your figure is way too high. I would put that figure more close to 30-35% (GDP share is around 26%)
Just in another thread I agreed that the US has potential to send Bitcoin into a deep winter if turning too anti-crypto. And it can definitely cause a deep panic with another 70-80% crash.
But: First, it's extremely unlikely that an anti-crypto policy in the US will be as harsh as in China in 2021.
If Harris is elected, then there won't be an anti-crypto policy in the US
at all. They will continue to make the market safer for average investors, which will increase the price. The ETFs were approved under Biden, and they are not anti-Bitcoin, which is a bunch of Republican-spread nonsense.
If Trump is elected, then literally anything can happen as he will not be connected in any way to US laws or the US constitution.
And second, I believe the US private crypto market could be close to saturation, other countries will very likely catch up in the next years and decades, reducing the US importance.
Maybe, but Bitcoin and cryptos generally, having no unique practical use (especially based on their market price), are completely dependent on their market perception. The US banning a product is about as negative as it gets.
The crypto ownership in the US is estimated at 50 million, [...]
That number is complete BS concocted by the crypto whales who are currently lobbying Trump. The real number is something like 10 million, as I understand it, and most of those are simple consumers using an existing app like PayPal and clicking on "buy Bitcoin" and buying a few dollars worth for fun.
Most of Bitcoin's supply is owned by a relatively small group of Bitcoin whales, if I recall.
US consumers, such as they are, certainly juice the price since they provide the liquid market these whales need, but the distribution of Bitcoin is very concentrated, as I understand it.
I mean, come on, if 50 million Americans were actually "Bitcoin fans",
this forum would have about 1000x more active users
