/*
$365 is a unique and intriguing cryptocurrency project that brings a fresh take on the crypto market, embracing humor and patience in a typically fast-paced industry. What distinguishes $365 from its counterparts is its distinctive launch strategy; the team behind the project undertook a year-long wait before its official launch, hence the name $365.
