At the begining you will use a lot of time to get to know the market, but later on you won't be using much time anymore so we can already say that time is not a problem for me.
Risk... risk is everywhere. It is just a  matter how well you can take it. Everytime you sit in a car there is a risk someone will crash in you and you could be gone, however you decide that risk is too low compared to the profit you get by getting where you want to be faster.
This same principle applies to Bitcoin market. You can't ask others about the risk, you need to proces it in your mind.
If you like my personal opinion the answer is definately Yes, because i believe in the technology it brings along.
