Hmm... Do you still regularly travel abroad? Maybe you can take advantage of this. How hard is it to send bitcoins to each other there? Maybe you can have a page where people can place orders and they'd have to pay you in bitcoins.
This would be like the setup you mentioned earlier except you are directly growing your cryptofund instead of taking fiat which you said you fear would further depreciate as Trump continues his trade war.
I do travel abroad for like once a year at most, but many of my friends haven't been abroad ever, and most of the others that have been just had been to Iraq or Turkey for once or twice.
But yes when I travel overseas I load up my whole luggage with the parts that I need
Sending bitcoins to each other is not a problem but some payment systems that let you make payment pages also ban us, like BitPay. I should design and program my own payment webpage from scratch if needed. Anyways thanks for sharing your ideas.
