Initial Investors who paid over 0.5 BTC have been given this deal also, we have already provided them

So if I invested 0.25, and someone else invested 0.5 they get 25% bonus and I dont.. that is pretty unfair to just make these rules after the ICO has started.
We are allowing top ups.
If your account goes over the 0.5 threshold, You will get 25% extra. so either way it doesn't matter, you can invest and get over that threshold if you require.
if you invested 0.25, You can invest another 0.25 and we will give you 25% extra on top.
As said on the initial promotion post you will need to email us so we can confirm as this is currently a manual process until our web developer finished the automated system.
Hope this answers your query.
I see these unfair too, but this is the way the world will always work: Money makes money, poor gets only poorer, and that's the way it will always be, sadly.
