What are the current financial requirements for extending a visa in Thailand, and why is there confusion about needing to show cash?

A user shared their recent experience applying for a second visa extension in Thailand and mentioned a new requirement to provide an updated bank statement along with their next 90-day report. The conversation surrounding this includes various comments about the financial requirements for entering Thailand, particularly the need to show 20,000 THB in cash. Some commenters noted that while they have not been asked for cash in the past, it remains an official requirement, and opinions vary on how strictly this is enforced based on the immigration officer's discretion.
