on entry they can ask to see 20.000 baht i believe the number is,
but this, to my experience almost never happens,
i guess if you show em your account and balance on a phone for instance incase it happens, this would be accepted. In other words, i would not worry about it,
they are probably busy enough handling the paperwork concerning modern travel anyways.
as for actual visa, it should be stated on the e-visa site if needed, stv is also different again, i suggest reading alot on the pages of your local embassy.
its 10 days, and there are many options, look around in this group and other, plenty of options. otherwise be more specific, like location, certain wishes, etc.
TBH, these kind of things happen all over the globe... and dont even start about private sensitive information, this is practically thrown on the street in most countries...
