How many hours does a day trader work?

I'm quite curious about the daily workload of a day trader. As someone who has been actively involved in the world of cryptocurrencies and finance, I understand that the job requires a high level of concentration and quick decision-making. Given the volatile nature of the crypto market, I imagine that day traders must be constantly monitoring price movements and analyzing market trends. So, I was wondering, how many hours does a day trader typically work? Do they need to be online and actively trading throughout the entire trading day, or is there some flexibility in terms of working hours? Also, do day traders typically work from home or do they need to be present in a trading office? I'm asking because I'm considering a career in day trading, and I want to make sure that I'm prepared for the workload and the demands of the job. Your insights would be greatly appreciated.
