There are cash-requirements for entering the country, is any currency accepted or it has to be baht?

Is it better to enter in CM or BKK or DMK?

If I am correct, for a single person entering with a Tourist visa you can be asked for 20.000. If you get an Visa Exempt it is just 10.000. And I thought the best way to enter is by land, but not on the south border. But I will not use land this time.

I got a 1 year stay of Visa history, so they might ask funds. I mostly hear bad things about DMK. I am likely to enter without visa and go for the Visa Exempt. I am from Europe.
