I just tried this today and it's easy and secured.
You will instantly see your wallet address reflected on the recent invests section.
.001 ETH isn't quite a big deal to put it here.
Before speculating, I strongly suggest to join and give this a try.
This review gives fair integrity to this lottery game. 0.001 ETH won't hurt the pocket yes.
Let's see what will others say too.
my question now is, for example i invested once, and i want to invest again with the same wallet, is it a new transaction or it will add to my previous one?
same question for my dividends.. that from the previous transaction, will current transaction automatically add to my dividends since i'm using the same wallet?
