Referral bonus isn't a waste of time. It's a powerful feature for gamblers who have influence inside a niche of society, like friends' group, family, internet circles, club, business or organization. These people are able to bring lots of users to the platforms they promote, consequently generating a very decent extra income from this activity.
On the other hand, if you spend a lot of time promoting your referral banners on social medias and see no positive results from that, then personally it must really be a waste of time...
Not a really waste of time if you are really that an active marketing guy or who does have lots of networks which you could potentially be able to hook up lots of people to join up under your link,
but if not then you are really just basically wasting up your time which does conclude out that this isnt for anyone or everybody.
Its not a waste of time if you are really that good at this but if not then it would really be that beneficial or something that you could really make use of those
amounts for your gambling or simply cash it out.
