Just out of curiosity.

How can you guys afford 1 bitcoin?? I see a lot of post saying just bought one bitcoin or bought 4 bitcoin and it absolutely mind blowing and inspiring but how?? I made some wrong life choices when i was 18 and just didn’t give a crap about financial stability but now i see how important it is but i came actually these posts about people buying 4 t 6 bitcoin and it baffles me.
