Already have 5% of a BTC (about half the amount you mentioned at the current price) but planning on getting moreMiravos, the best advice I can give you is this.
Lets say you plan to arrive in July 2021.
Lets say you have saved 12000 usd for this trip.
My advice - But 1 BTC with it and hold in a cold wallet. For sure, you will thank me in July 2021 as in next 6 months it will do much better than USD,
