Of course it does. Every cent of income makes sense especially to those who have nothing to depend on when it comes to financial resources. A small investment may give a small profit but if you try to save it can mean so much more than just a small income..
Also, in my opinion, I think with bitcoin growing every week , a small investment may be a fortune in the near future. Saving can make us see how small investments are worth the wait.
I think it is really better to start from a small investment if you don't have enough knowledge in investing. And also, your small investment will eventually grow as time pass by.
Correct, starting on a small amount is a very smart move, because in this way, you could prevent yourself on losing big amount of money in investing. Either big or small, it is still an investment, just like what you have said, you are going to earn through that small investment as the time pass by, but if you are going to be a boastful one and will just enter the Investment world without enough knowledge on it, then you're doomed.
