Who would like to pay 0.0001 btc fees every time he makes a bet, suppose he makes 100 bets then surely he will loose 0.01 at least and this is apart from what he looses in bets.
That is why luckyb.it has a chat lotto system the purpose of it is to cover all your fees and the more you wager the bigger the lotto prizes.
The only downside of the chat lotto system is that after the bet rains down, no one even comes to chat. And it's quite a pain if you chat actively, no one dares to bet as well.
The main reason I don't play there anymore is because it gives me a message that luckybit isn't available in my area whenever I go to the site. I know there are ways to get around that or send directly to the luckybit addresses but that detracts from the experience imo for a game that is marginally fun.
If you are from US or in a restricted area that gambling is disallowed, you could've saved the luckyb.it addresses if you want to play in the future.
