Rounded, right now a single IOTA is worth around $0.0000024. Yesterday it was worth $0.0000015. If the MIOTA price goes up to $500-$1,000 as some people have been forecasting, this means a single IOTA will be worth $0.0005 to $0.001.
According to this article by Financial Times in 2013, a person's age, gender or location is worth $0.0005. Right now this means you could exchange 208 IOTA for a single piece of this data, but if the value of MIOTA goes up to $1,000 it would no longer be possible to purchase an odd number of this data: 1 piece would be worth 0.5 IOTA, 3 would be 1.5, and so on.
Are value increases a problem for IOTA? Is there a plan for how to resolve this in a future where the IOTA price may exceed certain thresholds?
