The potential risks of using Bitcoin Ordinals include:

1. Network constraints: Critics argue that Ordinals might take up valuable space on the Bitcoin network, leading to higher transaction fees and slower processing times.

2. Market volatility: Like other cryptocurrencies, Ordinals are subject to market volatility, which might result in potential losses.

3. Unpredictability: Ordinals are a relatively new concept, adding an element of uncertainty and unpredictability to their future value and use cases.

4. Susceptibility to attacks: Despite their potential, Ordinals could make the Bitcoin network more susceptible to attacks, as fees are determined by the number of Ordinals.

5. Centralization concerns: Bitcoin Ordinals require the use of SegWit and Taproot technologies, which are not universally supported by all Bitcoin nodes and miners, potentially leading to centralization of the network.

In conclusion, while Bitcoin Ordinals offer unique opportunities, they also come with risks related to network capacity, market volatility, unpredictability, susceptibility to attacks, and potential centralization.
