Answered somewhere above
HK crypto exchange / OTC -> HKD -> Kasikorn︇ HKD account (Thailand - foreign currency account) -> convert to THB in branch -> paper︈ trail and fund import docs provided -> Buy condo
* note can send over in︉ HKD to THB account but fees will be higher with less control on currency conversion︊ decision.
** Note I know Kasikorn has foreign currency accounts as Elite established mine years︋ ago.
I previously (company) had a Euro account with bangkok bank for commercial but it︌ was costly to maintain and a pain in the a*s to do anything - with︍ Kasikorn you can have Euro, SGD , HKD and I believe $ (I don’t use︎ dollars so not 100% sure in that one).
Note there is zero digital access -️ it’s all managed in branch - normally the City/Provincial head branch, with Bangkok Bank it’s any branch I believe or was for commercial.
Not sure on other banks as never asked .
Reference OTC can’t give you any specifics - because a lot has changed over the past few years - will say a lot of Japanese OTCs route through Taiwan Merchant Banks.
In HK they route through Chinese or European rails or ripple (I know)
One that comes up immediately in google - so your research

Or look for established exchanges / crypto OTC regional companies.
