I myself am in the same situation and in my experience so far I find it kinda hard to be able to do profitable trading especially after a hard day at work. I find more profitable for the current situation if I find some good ICO`s to invest and maybe a few swing trades maybe for medium-long term. Daytrading is quite hard if you have a day job IMHO
Goodluck on your journey
If we have a job and our job is very important to us then for sure it's hard to choose trading because we will always prioritize our job.
Bitcoin trading or cryptocurrency trading can be possible for short term and long term, so I guess in your situation you can still trade but go for the long term as it does not really demand a lot of our time, holding bitcoin alone is already a good way of long term trading and it's really profitable.
