Frequently Asked Questions

Basics

What is usdt Trade?

USDT Trade is a general term for any type of Trade wherein bets are placed in units of USDT as opposed to a fiat currency or any other asset. Learn more about usdt Trade or the history of online Trade and bitcoin.

How to play?

Place a bet. Watch the multiplier increase from 1x upwards! Cash out any time to get your bet multiplied by that multiplier. But be careful because the game can bust at any time, and you'll get nothing!

Deposits

How do I deposit bits?

You will need to transfer USDT to the deposit address on your account page. If you do not have any USDT, we can recommend Coinbase if you are in the US (although the registration process is lengthy). Another great option is LocalBitcoins.com, which lists traders in your area willing to sell (or buy) usdt. You can also search online to see if there are any usdt ATMs near you. And remember, you can withdraw directly to the usdt address on your account page!

How long is the deposit address valid?

It is permanently attached to your account. You can save it, or use it for automatic funding, or whatever else you like. All payments to this address will be automatically credited to your account.

How long do deposits take to be credited?

We instantly credit accounts upon a single confirmation, which on average is approximately 10 minutes from the time of the transaction.

How do I withdraw USDT?

On your account page, you can transfer USDT to any USDT address you want. Small withdrawals (i.e. smaller than the balance of our hot-wallet) are processed instantly and you will be given the transaction ID immediately.

Larger withdrawals will be shown in your withdrawal page as "PENDING" and will require us to manually remove sufficient funds from our cold storage. Usually this process will take less than two hours, but may take up to 24 hours, depending on the time of day and other circumstances.

we deduct 5 usdt from any withdrawal amount as handling fee,the minimum withdrawal amount is 20 usdt

What is gross profit?

Gross profit refers to the sum of the profit from each game you've played without considering your loses.

Game

What happens if I disconnect from the game?

Upon detecting that you have disconnected we cash you out (assuming the game is still in progress). Regardless of whether your client is connected or not, the auto cash-out feature will work as expected (it happens on the server), and we highly recommend you use it if internet reliability or performance is a concern.

How high can the game go?

There's no real limit! However, if during a game we ever are facing a net loss of 3% of the bankroll or greater, the server will automatically cash out all players still in the game, forcing them to enjoy an early win and a sizeable profit. You can see in game what the current max win is (in the bottom right of the chart)

What is the most I can bet?

We currently have a bet limit of 10,000 bits USDT.

What is the bonus?

The bonus is a special prize that is awarded to the last people to cash out before the game busted. Getting the bonus is critical to skillful playing of bustabit, as it is the only way to overcome house odds.

1% of each player's stake goes into the bonus pot. So if there are 4 players, betting 400, 300, 200, and 100, there will be 10 bits in the pot. If the biggest player wins, he gets the whole pot. The site works out the rate he would be getting if he won, ie. 400 bits bet gives 10 bits bonus - or 1/40th bonus per bit bet. It then applies the same rate to whoever actually wins.

So if the 100 bit player wins, he gets 1/40th of 100, or 2.5 bits. That leaves 7.5 bits in the pot, which goes to the next best placing player(s).

Suppose the 200 bit player comes 2nd. He is due 1/40th of 200, or 5 bits. There are still 7.5 bits in the pot, so he gets the full 5 bits he is due - the same as if he had come in 1st place.

Suppose the 300 bit player comes 3rd. He's due 7.5 bits (300/40) but there are only 2.5 bits left in the pot, so he gets those and that's all. There's nothing left for the 4th or worse place players.

1% of games will instant bust (0x) and no bonuses will be awarded, all other games have bonuses equal to 1% of the amount wagered.

Fairness

What are the game odds?

The house margin is scaled between 0 and 1 %, depending on how long you hold. An additional 1 % is effectively taken from every bet and put into the bonus pool, which is distributed in its entirety every game. As a consequence, skilless or random play has—at worst—an expected return of -2 %, but it is possible to overcome the house margin by skillfully getting bonuses.

The numbers are baked into the game, so you never need to worry about it. We do not have a fixed house margin, as this would prevent highly conservative play (e.g. If you were only attempting to make $2 in a $100 game, a house margin of 1 % would be 50 % of your potential profits!). Our unique formula makes it fair for both highly conservative play (cash out early) and highly aggressive play (hold until you're a millionaire). All games are provably fair.

The exact formula for the houses expected return is:
1 % * (intendedCashOut - roomAmount) * (roomAmount / intendedCashOut)
But to really get a good sense of how this affects you, please use our handy odds calculator.

The other important thing to keep in mind is that every game has a 1 % chance of instantly busting. We do not make any money on it, but rather use this to fund the bonus scheme. This is an important consideration to make if you are playing in such a way that you never win the bonus.

How is the game bust calculated?

The code that decides the multiplier for each round is here:

https://github.com/moneypot/gameserver/blob/master/server/lib.js#L146-L158

It basically does three things.

First, it mixes the hash with the clientSeed (decided by the provably fair seeding event) using hmac-sha256

Secondly it gives a 1 in 101 chance of instant busting

Third, it works out what the multiplier would be if there was no house edge.

Fourth, it takes 1% off the multiplier and adds on 0.01x:

So half the time (other than 0x bust which we can ignore because they pay for themselves with the bonus) the multiplier will be 1.99x or more.

That means if we bet 1.99x we have a 50% chance of winning (again, ignoring 0x busts), and so the house edge is:

100 - (1.99 * 50) = 100 - 99.5 = 0.5%

The extra 0.01 that gets added on to the multiplier is half of the 1% that was taken off in this case, leaving the house edge at 0.5%. As the multiplier gets bigger, the 1% that is taken off gets bigger, and the 0.01x that gets added on becomes less and less significant, causing the house edge to tend to 1%

Is the game fair?

Absolutely! And we can prove it. Please see: the bitcoin talk thread for technical details.

What happens when the server forces people to cash out?

Under some circumstances the server will force people to cash out. The most common reason is that the game multiplier has gotten so large that we are risking too much of our bankroll (10 % or more). Another possible reason is unexpected server problems. If more than one person in a game is affected by the forced cash-out, we allocate the last cash-out bonus to a random player.

What other Trade places do you recommend?

A couple quick pointers: the lower the house edge the more variance you will experience which means a longer, more exciting gaming session. Bitcoin Casinos generally offer better odds, less fees and faster deposits and withdrawals than fiat based casinos. Be extremely skeptical of generous reward programs, bonuses (e.g. deposit bonuses), affiliate programs and the likes. The money comes from somewhere: you.

Instead of listing our favorites here, we'll defer to the excellent bitcoin strip

Do you have Trade addiction?

Trade addiction, also known as compulsive Trade, is a type of impulse-control disorder. Compulsive gamblers can’t control the impulse to gamble, even when they know their Trade is hurting themselves or their loved ones. Trade is all they can think about and all they want to do, no matter the consequences. Compulsive gamblers keep Trade whether they’re up or down, broke or flush, happy or depressed. Even when they know the odds are against them, even when they can’t afford to lose, people with a Trade addiction can’t “stay off the bet.”

Gamblers can have a problem, however, without being totally out of control. Problem Trade is any Trade behavior that disrupts your life. If you’re preoccupied with Trade, spending more and more time and money on it, chasing losses, or Trade despite serious consequences, you have a Trade problem.
