Donald Trump recently gained support for an ambitious proposal on cryptocurrency that would use 5% of the total supply of $BTC to pay off the massive US public debt. Currently, the total US public debt is about $35 trillion, and 5% of the total supply of Bitcoin is equivalent to about 1.05 million BTC.

To estimate the possible price change of Bitcoin if this plan is implemented, we can do a simple math calculation: assume that when the value of these $105 million BTC rises to be enough to completely cover the US public debt, considering that the public debt itself may also grow (for example, double), let's make an extrapolation.

Based on the above assumptions, if the public debt grows to $70 trillion and is fully covered by these 1.05 million BTC, the price per BTC will need to reach: $70 trillion / 1.05 million = $6,666,666. This calculation means that according to Trump's scenario, the price of Bitcoin will have the ability to rise more than 100 times from its current level.

Please note that the calculations here are based on a series of assumptions, and the actual situation may be affected by a variety of factors, including but not limited to market reactions, policy changes, global economic conditions, etc.
