if u want small winning use faucets in internet you can find many faucets,
if u want more than small winning you can use :
signature campaign , facebook campaign , twitter campaign and others
if u have skill you can sell as service here
for example design , coding and others
Faucets are waste of time, to much time for almost nothing. Signature campaign is always good thing, but its even better if you invest this bitcoins into something that will bring you profit.
I thinkg that designing, coding is best possible way for earning bitcoins or some other crypto currency, there is always work for people with this knowledge. And for people that doesn`t have it then gambling and trading, two most mentioned things on this forum.
