So if we count the bonus only and we make deposit 100USDT each then the total bonus is $400 for $400 total deposit.
Perhaps the wording "up to 400%" is a bit misleading, it should be "total 400% divided into 4 different percentage/bonus"
Well explained, I have never thought about it in this way. Some other casinos promote themselves in the same way, which is completely a tricky method of marketing.
Anyway, Bitstrike is a well furnished casino. The UI is impressive. And they are having the license from Costa Rica, which is uncommon in the crypto gambling industry.
