if you have to work all day, 8 to 10 hours perday, and always have to focus on your job. i think it's better to work and hold some coins for a long term not trading
It is very much difficult thing to do both the things and that too at the very same time. Trading itself is a very tiring job to do and you do need to spare lot of time for that. If you are having some permanent job, then it is better not to go for trading as you will be unable to do either of the things in a better way. Focus on one thing and work hard in order to make some good money later on.
Trading itself is sometimes harder than job really, your point is true. I know some users are capable of doing trading and job at the same time yet I don'y understand how they could manage to do this.
