I give you a better suggestion since you want people to deposit BTC and test your system.

Look at this guys: https://bitcointalk.org/index.php?topic=5140688.0

They are paying the users upfront to test their system and you can do the same. Ask the very trusted members in the forum to test your system and give them the required BTC to deposit.

This way users will not need to trust a new business with their own money.

Does the 10% bonus have any restriction on the plays after they are credited? As in, do I have to wager it or is it mine?

And is the 10% bonus applied to the bet amount or to the winnings?

As in, if I bet $10, and the bet is cancelled so that it returns to me my wager, am I getting back $11 or $10?

Sorry for questions but just like to be clear:)

OP I like some functions you offer but to be fair website looks very poor, better to get some good template, look your opponents, their website looks very attractive. Also when it says: 17 Available Matches, does this means we are limited in offered games? Because can't find more than one page too. It will be good for your business to make filter for games, for example make one block for La Leagua, another one for Serie A, Champions League and etc. This is really must to have even for beta project. Also include some details on betting, for example number of corners and others which top casinos offer.

Can you sign a message from an address with a decent amount of coins to prove that you do have funds to payout? What happens if the bet isn't matched? Is there any way to see the limit?

Edit:   

Will you make better margins, or do you plan to fade off into non-existence like many others?

I made observations, but I see that there are no answers. I will never pay a cent to a bookmakers without a license and with a mailbox address

I don't like that to deposit on the spirebets account you pass with coinbase by paying in USD.
I could experiment, but I must be free to use my BTC / ETH addresses both to deposit and to withdraw.
To withdraw you have indicated the fees to be paid, but it is not known if you pay taxes on deposits.
The 10% deposit promotion is not published on the site.
Finally, a very important aspect is to know the maximum bet you accept, because if you deposit 1 BTC I don't have to have the negative surprise, that you only accept 0.2 BTC of maximum bet

I will wait for another crypto to enter as a payment, the site looks perfect I'm very happy to see it spirebets looks like Directbet but if you add some well known cryptocurrencies it will definitely be crowded.

As most members mentioned it has come with some features of directbet that attracted the people towards gambling in large numbers.. Now this being completely dedicated to the football match betting over the early days will get more people into it, as most of the sports betting people always prefer football over other games. Some form of promotion too is a must during the early days to reach people about the existence of spirebets.

i thought that beta testing means we can use the website freely without using any bitcoin and can you show a minimum bet for each bet?

Why would you launch a website when it is in beta testing? If a user comes across a bug or loses his money, your website will get a bad reputation and people will avoid it. You just support football games which limit your market to an only a specific audience.

The odds on the games are awesome I really get pissed off when I see freakishly small odds to teams. Although games can be played without having an account the registration is very straight to the point and easy I would be placing my bet that this project would do well

I was also thinking the same thing as I like the feel of directbet.eu when they were around as it was a great way to just put in a quick bet before a match started and never needed to login and go through things that you normally would with having an account on the betting site you were using. I have about three different accounts for sportsbetting sites and actually lost one and trying to recover it right now. Just too many sites can be a burden for some who have too many sites to remember login information for can be a pain.
Love the idea of no registration required if you are just wanting to place a small on the go wager on a game.
Thanks for giving us this option again and will be using your site in the very near future and hoping to see more sports offered in the coming months as you described.

I have seen your site but I see the Log in and Sign up button, why the feature is there? while we can play without making an account just enter the payout address under Betslip. But btw good luck with your website launch even though it's still beta I'm very interested in playing there.

Finally there is a new sportsbook that is a bit similar to directbet where users are not required to have an account to place bets. I haven't checked about the odds you offers compared to other sportsbook sites, so I have no ideas whether your odds is competitive enough or not. Coming to your site, I think it is better if you have a filter or categorization of the sports. Sorry if it is available already for those who have an account but I cant find it without an account except the search function.

Since you are testing the BETA version and very new to the market, my suggestion is to giveaway registration bonus (without any need of depositing, may be to some number of users only. Say first 500 as example) with some very hard goal to achieve like 30x play through of the initial bonus for minimum odd of 1.8 or 1.9.

This way new users will be attracted to have the free bonus.
