Should I buy more or hold in HYSA

In the next two weeks I’ll receive $8,400 post tax.

I’m owed $6,400 in a tax refund I should get next year in the early months.

I have 0.1 BTC, and around $2,000 in cash right now.

I’m going to Shanghai where I’m not sure how much my spending will be (my apartment is paid for already). Most spending will be restaurants and travel within China. My best estimate is somewhere around $1,000 a month. I’m there for 4 months, so $4k spend.

Then I go to south east Asia for backpacking where I’m budgeting around $500-750 a week, though I’m not positive on these numbers. I think I can pull off $500 a week all in, for 17 weeks, so call it $8,500.

So to sum it up, I’ll need about $13,000 to spend over the next 10 months or so, before I move back home and have no expenses with a job starting soon after.

Counting my tax refund and my income and my current savings plus my bitcoin I have, about $23K. That’s about a $10k cushion.

Would any of you buy more bitcoin in this situation? I’m thinking if I resource constrain myself I may be more inclined to just spend less, and if I really need it I could just sell the bitcoin. Idk not sure what to do here, these prices seem great
