Which types of transactions are not suitable for blockchain storage?
What are the scenarios where blockchain may not be the best option? Specifically, how do privacy concerns or factors like transaction speed and cost impact the decision to avoid blockchain? Are there transactions that don't align well with blockchain’s transparency, or those that involve large volumes of data? How do high-frequency transactions, privacy needs, and storage capacity influence blockchain's suitability? Insights on where blockchain may not be the ideal choice would be helpful.
