BTC's value as a store of value: while it's true that BTC's value is determined by the market's willingness to pay fiat currency for it, the same can be said for any currency or asset. The intrinsic value of a currency or asset is ultimately determined by its usefulness and scarcity, both of which BTC possesses. Additionally, BTC's scarcity is programmed into its code, making it more predictable and transparent than traditional fiat currencies.

BTC as a hedge against inflation: it is important to note that BTC is a relatively new asset with a volatile price history. In the long run, BTC has shown a tendency to appreciate in value over time, making it a potential hedge against inflation.

BTC's network stability: while it's true that a collapse of the BTC network could occur if there is a significant drop in mining activity, this is an unlikely scenario given the incentives that miners have to continue mining. Additionally, there are measures in place, such as the difficulty adjustment algorithm, that ensure the network remains stable even in the face of changes in mining activity.

Dollar-cost averaging: yes, most don't have $1.25 million to invest in BTC, but dollar-cost averaging is a valid investment strategy that allows investors to accumulate BTC over time without having to time the market. By investing small amounts on a regular basis, investors can potentially benefit from the long-term appreciation of BTC without having to make large, risky investments all at once.
