정답: B. 상승
How to solve: The sentence states that investors were '기뻐했습니다' (happy). Investors are happy when the value of their investment increases. Therefore, a word meaning 'rise' is needed.
Choice analysis (EN):
A — '하락' means fall/decline. Investors would not be happy if the price fell.
B — '상승' means rise/increase. If Bitcoin prices rise, investors are happy. This is the correct fit.
C — '유지' means maintain/keep. While stability can be good, 'maintenance' alone doesn't typically make investors 'happy' in the sense of gains.
D — '고정' means fixed. A fixed price doesn't imply gains that would make investors happy.

B — '고정성' means fixedness/immutability. If fixed, it would be perfectly predictable.

정답: B. 투자
How to solve: The sentence talks about a '심리' (sentiment/psychology) growing stronger regarding Bitcoin. People typically engage in financial '투자' (investment) with Bitcoin.
Choice analysis (EN):
A — '소비' means consumption/spending. While Bitcoin can be spent, the context of '심리' becoming strong usually refers to investment intent, not just spending.
B — '투자' means investment. '투자 심리' (investment sentiment) is a common phrase and fits the context of Bitcoin perfectly. This is the correct answer.
C — '낭비' means waste. People don't typically have a strong 'waste sentiment' towards an asset they acquire.
D — '포기' means abandonment/giving up. '포기 심리' would mean people are giving up, which contradicts '강해지고 있습니다' (getting stronger).
