BitWhisk.io ✦ new Bitcoin mixing service ✦ testers evaluations

[digaran]

Well, I could say that, from your replies that you really care about having a long-term business reputation in mixing industry. giving 0.1BTC to people in a forum to test your new service is a waste of money. what I had in mind, I would like to see you having 1BTC in escrow, and another one for mixing in your hot wallet. if you don't have that much, you could start with 0.2BTC escrowed and 0.2BTC in hot wallet.

You need more coins than 1-2. if you are going to depend on your customers to increase your balance, you'd get nowhere.

I just tried your service. The interface is simple and very easy to use. Your mixing mechanism is also pretty straightforward. Anybody who has a basic understanding of a mixing service should not have experienced any trouble at all when using BitWhisk. Didn't notice any significant delay in the mixing process, good one.

Hope you guys could find enough funds to scale up the mixing capabilities. Good luck!

I have received ~1.25mBTC to test and review this mixer. I have chosen to receive 57% of my mixed coins to my address #1 after 8 hours and the remaining 43% to my address #2 after 6 hours. My first impressions: I really liked the minimalist design of the website and how everything you need to know about your order is shown in the "Order status" page. I'm still waiting for my coins (because of the delay), but it's great how I can easily check when they will are scheduled to arrive - which is great.

I have tested multiple mixers and if this one had a reputation, I would probably choose them over other famous mixers like BitBlender (for simple send->receive mixings, otherwise, I still prefer ChipMixer due to the way they work with the chips).

I will update this post when I receive my coins in ~7 hours.

Edit: I received my coins in the designated time without any delay. Thanks!

Just a quick suggestion: Use segwit. Help the network and save some fees

giving 0.1BTC to people in a forum to test your new service is a waste of money.

Why?

what I had in mind, I would like to see you having 1BTC in escrow, and another one for mixing in your hot wallet. if you don't have that much, you could start with 0.2BTC escrowed and 0.2BTC in hot wallet.

Escrow is good but it's not 100% scam-proof. BitMixCoin had 10BTC in escrow for some time and they lowered that amount to 5BTC without any public warning. They could have wait until they had 10BTC from costumers, ask the escrower to half the amount in escrow and still profit 5BTC if they decide to scam everyone. If you choose to setup a escrow and then decide to get the coins back or lower the amount, at least warn everybody a few days in advance.

TryNinja, thanks for the review.

Yes, after other testers finish we will upgrade bitcoin-core to 0.16.0 and switch to using segwit addresses.

Best,

I have tried the website to mix 0.001btc and here is my review: the design of the website is very very simple and easy to use. Even if you have not mixed any coins in the past, there are good instructions on the website and it is impossible to dont understand how it works. I mixed my coins to two different addresses and I put a delay on one of them. The coins were delivered at the exact time. I dont have anything else to say, the fees are the same as on other mixers so as the other details. What will make difference is how you promote your website.

[BitWhisk.io]

Hi guys! First of all, thanks to all testers, your help is appreciated.

We worked hard to make our service better and there is a number of quite important updates! See the list below.

1) We switched to using segwit addresses.

2) Smart resending policy. Namely, we resend your transaction only if the following conditions are met:

• The transaction hasn't been confirmed for 5 blocks since sending;
• The change of unconfirmed transaction is needed to process other users payment.

So, basically, if no heavy load is present, then your transaction will wait for confirmation infinitely long. We updated FAQ-section with explicit declaration of these details.

Hence, the only possibility when your payments are extra-delayed by our fault is that we need an unconfirmed change. The system of order status checking should notify you about such situation. However, such cases should be quite rare (see next point) and if this happens we will refund your service commission.

3) We updated our mixing algorithm. First, we minimize the number of transaction inputs and then minimize the change amount for given number of inputs. This adds randomness in our transaction history and minimizes unconfirmed change amount.

4) Small technical updates concerning calculation of minimum incoming amount for the order. Suppose optimal miner's fee rate is 100sat/B and you specify the rate of 10sat/B, then min. incoming amount will be calculated using optimal rate, i.e. 100sat/B. Just to exclude dust payments from handling.

Currently, the only and main drawback is that we do not have enough BTC to mix

We would like to test the system before making an official ann. If you are interested, write your address here or in PM.

Best regards,
BitWhisk team

I'd like to help test the service; I worked for coinmixer.se for a couple of months, so I have a bit of insight on what mixing services is concerned

Hi,
I want to try it, if still available.

Review:
First, the mixing website UI is straightforward and easy to use, but I don't know how the mixer can attract others' attention and beat other famous mixers.

Hello BitWhisk.io team,

Thanks for introducing SegWit! It might help with making your service popular after you officialy announce it. Since you upgraded to the latest Bitcoin Core, could you tell me if you can send to Bech32 addresses?
I would be glad to test your service again after improvements.

Since you upgraded to the latest Bitcoin Core, could you tell me if you can send to Bech32 addresses?

Now, all generated incoming addresses are p2sh-segwit, this already should greatly reduce the miner's fee.
We do not currently support bech32 format (the system will consider bech32 address as incorrect). Could you tell what are it's benefits over using p2sh-segwit?

Should we expect that bech32 will become the main format of addresses in future?

New bech32 format is technically a native SegWit, using it would decrease the transaction size which would lead to lower transaction fees [1]. However, not every wallet supports bech32 format, yet, so I think you should stick to Nested (P2SH-P2WPKH) for some time. Although, it would be nice to be able to receive mixed coins to bech32 address. Feel free to PM when you will decide to implement it.

So, I tried the service and it works perfectly fine. Simple interface; easy way to adjust the fees and the bitcoins were really mixed (after checking all the inputs and their inputs). Time delays working fine too

I hope they have good luck and that they get many investors

[btckid001]

I want to have a try and make comments if available.

  Yeah, another direction to develop. We will enable the possibility to send to bech-32 in a few days.

I have used this service with 0.001 btc.Here is my review.It has a user very friendly interface.Using segwit address makes it possible to reduce the miner's fee much.Also,fee is less when compared to other existing popular mixer services.More over,letter of guarantee is provided which seems missing in even other famous mixers.I hope that this service would definitely attract and help lots of bitcoin owners who wish to use legit mixing services and stay anonymous.

I have received my coins in the appropriate time without any delay.

[BitWhisk.io]

Dear HasHe and csmiami, it is very pleasant to obtain such good reviews from you.

However, yesterday we sent coins for testing to three persons and server processed only one mixing request. And then two reviews came up. What should we think? Does it mean that one of you two (we cannot know who) did not mix any coins with us?

We are still testing, so if both of you indeed mixed coins then something very strange is happening

Best,
BitWhisk

I would like to give a review for your service as well.
However, if you do not trust me, i can test your service with my own funds and then you can send them once i am done with testing.
But here is my BTC address if there are still spots available for the testing queue: 1ACCs9LEvxV2o4zSWKMUYUHp1DKTrAHFcU

Dear Sellingaccs, did you mix 1mBTC with us? If yes, we apologize for delay, you helped to open up a small bug when sending too small change.
Anyway, the bug is fixed and the payment is processed.
