Deflation is not relevant for a transaction
What are you trying to say with this? Cause I'm stuck between the very literal and wildly confusing.
I will say, regardless of your further explanation, that deflation makes transactions less likely to happen, which is the whole point of a currency to begin with. Would you rather pay a debt to a friend off with dollars or a cryptocoin? Cause my money is that most people would say the dollars since the crypto could grow, whereas the dollar is always shrinking. A speculative asset is not something most people would give away like they would money.
