BitcoinDood: Thanks for taking the time to do this interview. If you don’t mind could you tell the readers who you are and what your relationship is to

POSwallet: Thanks for reaching out to me. I am the lead dev of, a group of cryptocurrency die-hards that have been involved in this field since 2013. I’ve got a 15 year background in web programming and a doctorate in database engineering.

BD: POSwallet is an online staking pool. Could you tell the readers a little about the site and what a staking pool is for anyone that may not know?

PW: Sure, great question. About 6 months ago I ran into a problem where I had ~30 different wallets running on my main computer, essentially bogging down the computer enough that it became unusable. I bought another rig to just run the wallets; however, did not have a good system to keep track of my balances and stake frequency. The core of the software package originated as a solution to this problem.

A staking pool is a service where users deposit their coins, the coins are combined, then staked at a higher frequency than if the user staked their coins in a solo environment. This type of service allows for a much more consistent stake rate for the average user.

BD: What are some of the benefits of joining a staking pool over say, installing multiple wallets on your own machine and staking all the coin yourself?

PW: Computer resources, electricity costs, carbon footprint, and constant upgrades/wallet maintenance are all saved/eliminated by joining a group staking pool. Many users do not have the technical prowess to manage a few dozen altcoin wallets – services like bring the complex world of cryptocurrencies to the masses. Frankly, it is easier to set it and forget it (throwback to the 90s) than to constantly manage a few dozen wallets.

BD: At the time of this writing you have over 60 different wallets that you offer for staking. A lot of coins are using POS now. How do you decide which coins/wallets to include in the POS pool? Do you ever take coin/wallet requests for new additions? Is there any type of voting system in place?

PW: The initial ~30 coins were chosen because I owned those coins – since then, I have been adding coins as they are requested by the user base. I do not charge devs to host their coins; however, I do ask that ~0.10 – 0.25 BTC equivalent of said coin are loaded into the faucet/staking wallet. I try not to refuse any coin addition requests, as long as the coin is legitimate and has a compile-able wallet and reputable website/ANN.

BD: Without giving away any secret company info, can you talk about the type of equipment you’re using to run the service? How many machines does it take to keep something like this operating at full capacity? What are the energy requirements compared to say a mining operation?

PW: Keeping 65 blockchains synced up and processed is a surprisingly complex task. At last check, the database system supporting the website is ~20 GB large, in addition to the ~100 GB of raw blockchain data for all of the coin wallets.

In terms of hardware – we have multiple server setups for redundancy and different security measures. The number of servers is somewhere between 6 and 16 :). The overall hardware setup is still much less energy-intensive than a large scale mining setup, as CPUs/SSDs are generally much less power hungry than GPUs.

BD: Many people worry about the security of leaving their coins in a pool or on an exchange. It seems like every couple months or so another exchange is announcing that they’ve been compromised and are missing funds. On your website it mentions a review feature, and that you match balances in a cold wallet. Could you elaborate on that a little more and explain what that means?

PW: This is one area where we wanted to be different than other websites. First – we have coins stored in cold-storage acting as insurance against user deposits. Second – a large percentage of transactions are manually approved after review; there is a complex security system that monitors (and flags as necessary) all transactions across all of the user addresses. Although this does lead to a delay for a small number of transactions – generally ~30min delay for <5% of transactions – it also leads to a much more secure experience overall.

BD: The Dood never really rushes into anything. I recently transferred over a small amount of my portfolio to see how the service works; I’ve slowly been adding more. I have to say, The Dood’s impressed. Even with the little bit of coin I transferred I began seeing immediate returns in stake. The best part is I’m not tying up any of my system resources by running multiple wallets on my own machine. Can anyone join the pool? Is there a minimum balance you need of a particular coin? Can a guy do this with his faucet earnings if he wanted? What type of investments and returns can someone expect with something like this?

PW: Anyone and everyone can join – the real goal of is to bring altcoins to people who are not as tech-savvy as the folks that populate the bitcointalk forum. There are no minimum balance requirements and many users only have the faucet balances in their account (while still earning stakes). In terms of ROI, does not guarantee any return on investment – there is risk in altcoin investments. We are not financial investment advisors and don’t promise to be able to tell the future. That being said, depending on which coins a user chooses to invest in, the ROI can be relatively large. There are multiple PoS coins at that stake > 100% per annum. Remember, a higher interest rate is always coupled with higher risk.

Overall, even with the risk, altcoins present a possibly substantial source of income in a world full of negative interest rates.

BD: What about fees? Are there fees for deposits? Fees for withdrawals? Any minimum time required to store or withdraw coins? Any penalties for early withdrawal or anything like that?

PW: There is a flat deposit fee of 1%, which covers faucet refills and server/operating costs. If the 1% fee generates more coins than required to keep the faucets full and the lights on, the fee will be paid back out to the members. We have a few ideas on how to do this in a fun way.

There are account requirements – no penalties for withdrawals either. One thing to note: once a user sends coins to a address, there is an initial vesting period (different for each coin, but generally 3-4 hours) where the coins can not be immediately withdrawn. This was added to cut down on users depositing, waiting for a fast stake, then immediately withdrawing over and over; we want to keep transaction cost and server load overhead down where possible.

BD: Is there anything you would like to mention that wasn’t talked about earlier or any special site features that I may have missed?

PW: I really appreciate you taking the time to talk with me – great questions overall. If anyone has any more questions, please head over to and chat with me in the support center. Also, we are always looking for more/new/awesome PoS altcoins to add to the site.

We are always adding more features – blockchain explorers for all of the supported coins are currently under development, and the faucet has sent out over 25k claims as of this morning. If you have a good idea for a feature at , please send it our way!

BD: When it comes to money and finance, cryptocurrency has the potential of changing everything. I always end every interview with the same last question. Where do you see cryptocurrency going in the future. Can you share any visions, thoughts, or predictions of where you think this is all heading?

PW: I expect explosive growth in total cryptocurrency market cap over the next 2-3 years – by 2019, the total cryptocurrency market cap will be > $200B USD. We are still very much at the ground floor of this movement; however, until apps start reaching out to every day internet users, growth will be slow. We need to work together as devs to drive adoption by both techies and non-techies alike.

The Dood would like to thank the lead dev of for taking the time to answer these questions and do this interview.

Thanks for taking the time to read this article. The Dood hopes you found it as fascinating and informative as I did writing it.

The Dood is not affiliated with POSwallet in any way, other than using the service himself. I do plan on doing a website and product review some time in the future. For now, all I’ll say is I’m happy with the service and everything seems legit. Remember you should always hold your own public and private keys, but this is a great way to stake multiple coins at once without tying up all your system resources. I wouldn’t stake my life savings on here, but this is a great way to stake a fraction of your portfolio and start earning some interest on those coins that may just be sitting around on an exchange or in a closed wallet. Not giving out advice here, just saying 🙂
