Meaning: 'Point' refers to a specific moment or level, particularly in this context, indicating a critical stage of bursting.

Wrong options:

• spot: 'Spot' refers to a specific location or place, which does not fit the idiomatic expression used here.
• deviated: 'Deviated' is a verb that suggests a departure from a standard or norm, which does not grammatically or contextually fit the phrase.
• touch: 'Touch' is a noun that can refer to contact or a slight degree, but it does not complete the idiomatic expression appropriately.
• sense: 'Sense' refers to a perception or feeling, which does not align with the context of a bubble bursting.
• based: 'Based' is an adjective that indicates foundation or support, which does not fit the context of bursting.

Correct answer: touch

Explanation: The word 'touch' fits grammatically and contextually as it completes the phrase 'lost touch with reality,' which means to no longer be aware of or connected to the actual situation. This reflects the sentiment of the text regarding Bitcoin's value.

Meaning: 'Touch' in this context refers to a connection or awareness of reality.

Wrong options:

• point: 'Point' does not fit here as it does not convey the idea of connection or awareness in relation to reality.
• deviated: 'Deviated' suggests a departure from a norm, which does not fit the context of losing connection with reality.
• sense: 'Sense' refers to perception, but it does not convey the idea of losing connection as effectively as 'touch.'
• based: 'Based' indicates foundation, which does not relate to the concept of awareness or connection to reality.
• spot: 'Spot' refers to a specific location, which does not fit the context of losing awareness.

Correct answer: based

Explanation: The word 'based' fits grammatically as it describes Bitcoin's lack of foundation in measurable value. This aligns with the context of comparing Bitcoin to other investments that have tangible value.

Meaning: 'Based' indicates that something is founded or grounded on a particular basis, in this case, referring to Bitcoin's lack of measurable value.

Wrong options:

• point: 'Point' does not fit grammatically as it does not describe a foundational aspect of Bitcoin.
• spot: 'Spot' refers to a location and does not convey the idea of foundation or basis in this context.
• deviated: 'Deviated' suggests a departure from a standard, which does not fit the context of describing Bitcoin's value.
• touch: 'Touch' does not relate to the concept of foundation or basis, making it unsuitable here.
• sense: 'Sense' refers to perception, which does not convey the idea of being grounded or based on something.
