Abstract
We prove that if is a random completely multiplicative function, conditional for each prime , the probability that for all is as . This solves a conjecture of Kucheriaviy, who has a complementary result showing this exponent is sharp. We also prove that almost surely the partial sums of change signs infinitely many times, solving a problem of Aymone.
