How much cash should I carry to Thailand?

Hello, I'm planning a trip to Thailand and I'm wondering about the appropriate amount of cash I should carry with me. With the convenience of digital payments and the fluctuation of currency exchange rates, I'm a bit uncertain about the right balance. Could you please advise me on the general rule of thumb for carrying cash in Thailand? I understand that having some local currency for small purchases and emergencies is advisable, but I'm not sure if I should bring a significant amount or just enough to cover my initial expenses. Additionally, are there any restrictions or regulations I should be aware of regarding bringing in cash or using credit cards in Thailand?
