In my opinion I think you should have a savings for sure. You need have enough emergency money around for when things get difficult. As far as investments are concerned, gambling shouldn't even be considered an investment. The best investment in my opinion is bitcoin itself.
The best way is separate your money in saving for your cost-living and emergency case, then you can invest the rest. Atleast the investment dont interfere your cost living, so you could avoid to lose everything.I think it is better to invest in Bitcoin and hopefully wait until price increases. It is the better way to make money. Just my opinion 
INvest Vs trading
you can invest for long time may be 10-20 years but for trading you need only 1second - 1month ( mide - term)
I m a trader and im trade bitcoin for some % profit
I don't know if you lack better understanding of English or you are just plain stupid. There is a difference between knowing what's wrong and fearing something. Fears don't let a person sleep at night, while making a right or wrong decision is all about being wise and having complete knowledge and information regarding aspects which involve the decision making process. You know what you should fear? Meeting someone exactly like you, your brain will hurt from the stupidity.
Sometimes fear and knowing are related, like when you have known about gambling side effect, then you feel afraid to try gambling. PS: well you shouldnt blame other person because his misunderstanding, since not all people are english native
