its wise my friend, actually you need some time to earn from your trading investment, so while waiting for it to grow your work can help so much with some other expense. and on the other hand, you can try other types of crypto currency related jobs, try to search some or even try what other advice to you. so atleast you can earn more for your investment, without taking out from your oun pocket. and at the end of the day, the bitcoin you invest is holded safely. but it is still up to you.
