I personally can't find any cons yet, but for anyone who might be looking for a structured clock in/clock out schedule, Hashgraph might not be the right choice. It comes with the remote startup environment + a global team, where on one hand you can enjoy flexible work hours (pick up your kids in the morning and do some extra work later in the evening), but on the other hand, you need to have strong organizational skills to know when to stop working for the day and have some rest to not burn out by accident.
