The volume has gone down (not dramatically so) a bit since currently Vietnam is in lockdown and all borders closed (so no tourists are coming to use the machine which where a minor, but significant part of our user base); overall we are holding up quite well though.
In Vietnam (almost) everybody is quite aware of the situation and use of facemasks / hand sanitizers is widespread. Our firm also switched since last month to basically fully remote office and any physical interactions which still take place, are conducted with outmost care to avoid getting infected (many Vietnamese people live with and/or close with their parents and elderly family members which make it even more important to not become a spreader).
I've been following a few BTCATM projects over the past two years. The numbers are hard to ignore in terms of proliferation, and I am from Southeast Asia where in my own capital 2 ATMs were installed years ago but sadly, fell into disrepair (that I know of anyway based on the bitcoin atm radar of circa 2016).
Good luck to you. It's going to be bad for most businesses -- crypto not excluded -- but we will all come back bigger than ever!
