smoking will give you many big disease as like Cancer, Asthma, Stroke etc. But Bitcoin will give you a great future. I mean BITCOIN will change your life.
Smoking is an individual choice, so I don't want to comment on it. The important thing here is that no one should be left behind. Those who have heard about Bitcoin can allot a small amount every week or every month, to invest in BTC. In case of OP, he has stopped smoking and decided to invest in BTC using that amount. For others, it is not necessary that they need to stop hobbies such as smoking. They can secure the funds from other sources, as per their convenience.
