For fun, I checked other key variants for 1iJuniorTV and out of 15 variants, only about 5 matched the prefixes.
Again:
Can you explain this? As far as I know, vanity split key matches should be correct and not have a "1 in 6" chance.
When I did my
split key vanity giveaway, every match I found produced the desired address.
if you used VS you got lucky. The other one discards child keys automatically, JeanLuc should have implemented this into vs.
