Coincidence, but true!

2015: spent 0.13 BTC to pay for a domain name (~$10).
2017: spent 0.13 BTC to pay for a Trezor (~$100).
2019: spent 0.13 BTC to pay for a mobile phone (~900).

All of the above items are now worth ~$13,000.

It just shows how fast and how much BTC has appreciated in value.

It's OK to shave off small fractions of profit to have some fun (YOLO), but know that the items you buy will soon be the most expensive you'll ever purchase. Guaranteed.

Sanity advice:
Sell profit fractions for fun.
Keep cold storage cold!
