If Trump's cryptocurrency reserve plan is implemented, it may have several long-term impacts on the supply and demand structure of Bitcoin. On the demand side, it could significantly increase the demand as the government's purchase would boost institutional and investor interest. However, on the supply side, the limited supply of Bitcoin might lead to price hikes, potentially causing some miners to increase production. Overall, it will likely reshape the market structure, making Bitcoin more recognized but also more volatile.

This plan could indeed have a significant impact on the Bitcoin market dynamics, affecting both demand and supply sides. It will be interesting to see how the market adapts to these potential changes.
