Heavycoin (HVC) is a new CPU only mined crypto currency that is just launching/launched and we have compiled for Windows the modified cpuminer software that you can use aside from the wallet to solo mine the coin at launch, while the official pools start working properly. Heavycoin uses a new algorithm called HEFTY1 that makes the coins a promising alternative to the likes of Primecoin (XPM) as a crypto that can only be mined on a CPU (at least for now). You can use the miner to solo mine on Windows systems after HVC mining officially starts on March 8th 12:00 UTC. The archive also includes a version of the minerd for the http://hvc.1gh.com/ pool, so far the only working pool for Heavycoin. Note that the pools apparently uses a specially modified version to work for them and it might not work on other pools, that is why we have included both versions in the archive.

Heavycoin (HVC) is a HEFTY1 CPU-only Ultra-secure new crypto currency with decentralized block reward voting. Get ready to mine, mining starts on March 8th 12:00 UTC! Heavycoin has the potential to achieve massive adoption and become a wide-reaching crypto-currency. With a strong community behind it, Heavycoin could even challenge Litecoin for position number two next to Bitcoin. With this in mind, the Heavycoin launch is taking place in multiple stages to encourage a diverse body of early adopters and stakeholders. Heavycoin will also leverage multiple launch strategies for maximum impact.

Heavycoin mining will open up a new dynamic because of decentralized block reward voting. Miners who are greedy and have little stake could vote for the maximum block reward of 1024. However, this will increase the supply of Heavycoin and decrease their profits. Other miners, who are not greedy, or who already have a sufficient stake, might vote for a lower block reward — even zero — in order to decrease the supply and to slow the minting rate. Either way, this is going to be interesting!

Intially Heavycoin starts with a zero block reward. The very first miners will have the first opportunity to solve blocks and vote on what the first democratically selected block reward should be. The first 100 blocks (3.3 hours) will decide the starting block reward. From then on, block reward voting will continue, but the votes are counted and averaged every 3600 blocks (5 days).

Heavycoin is configured to mine and vote by default, with a default vote of 512 HVC. If you want to change your block reward vote then see “How to vote” section of our website. Otherwise, to disable voting then see “How to mine”. When mining is enabled, every time you mine a block your wallet will automatically cast a block reward vote. The Heavycoin network automatically averages these votes every 5 days (3600 blocks) and sets the new block reward accordingly. The block reward is the average of all 3600 votes over the previous voting period rounded to the nearest integer.

We have been asked by a reader about our opinion and to to check out a website called BTC Arbs that supposedly offers daily returns of invested money or Bitcoins of 0.1% to 10%. What the website claims to do in order to provide so high daily returns on invested money or BTC is arbitrage of Bitcoins between different exchanges. The website seems to be well designed and looks very convincing in terms of information available on it. The minimum investment is $50 or 0.05 Bitcoins and the site accepts direct Bitcoin transfers as well as money deposits from investors with no maximum investment amount. The website even has a Results page a daily return rate on your investment, so everything seems really legit, especially if you do not look into things in detail and are captured by the high profit you are promised. The problem however is that the website is most likely just a scam and another well made Ponzi Scheme that is there to make some quick money at users’ expense!

What should raise a warning in this websites and other sites at first is the very high return rate or the so called high-yield investment program (HYIP) that you are being promised on a daily basis, this is the most common thing for Ponzi Schemes that attracts user’s attention and fuels their greed a lot. Up to 10 percent per day means you can get rich very fast for doing nothing, yeah, right… in reality just the opposite. The next thing you should look into is who is behind the website, and the only thing about that you can find on the website is that it is based in Switzerland, however there is not info about the company or address or event at least mail or phone to contact them on the Contact page. Furthermore the website claims to be created in November of 2013, but a quick whois returns different data – Creation Date: 2014-01-04 20:13:00, anonymous registration and hosted in a web server in Malaysia. It all seems less an less legit and clearly the website claims things that are far from true…

You can see that some people have already tested the BTC Arbs service and report making some money already on top of their investment and withdrawing their earnings successfully. This is a normal way of operation – the first “investors” in a Ponzi Scheme do get paid in order to convince them that everything is working as promised and to encourage them to invest more and more into the service and to bring other people too. In reality however the “earnings” the earlier “investors” are getting do come from money that new users brought to the service are investing into it. And as soon as the authors of the Ponzi Scheme decide to get away with the all the money everything will fall down and some people will actually loose money. But even in this scenario if you are one of the “early investors” and use the service for just a few days with small amount of Bitcoins (never invest real cash into such Ponzi Schemes!!!) you might actually end up making some cash. Never, never and NEVER invest long term in a Ponzi Scheme or HYIP website, but what is even better thing to do is to stay away from such websites! We would not recommend to use services such as this one, even if there is some small chance to actually profit from using them, because this will be at the expense of somebody else just like you!

In short – if something looks too good to be true, then it probably is and you should be wise and best avoid it.

High-yield investment program (HYIP)
A high-yield investment program (HYIP) is a type of Ponzi scheme, an investment scam that promises unsustainably high return on investment by paying previous investors with the money invested by new investors. Most of these scams work from anonymous offshore bases which make them hard to track down. Operators generally set up a website offering an “investment program” which promises very high returns, such as 1% per day or even more, disclosing little or no detail about the underlying management, location, or other aspects of how money is to be invested. Or giving you a nice story about the whole thing such as BTC arbitrage, that may sound believable to newbies or people that are generally not very experienced and haven’t suffered yet from such a fraudulent scheme.

Ponzi scheme
A Ponzi scheme is a fraudulent investment operation that pays returns to its investors from existing capital or new capital paid by new investors, rather than from profit earned by the individual or organization running the operation. Operators of Ponzi schemes usually entice new investors by offering higher returns than other investments, in the form of short-term returns that are either abnormally high or unusually consistent. The perpetuation of the high returns requires an ever-increasing flow of money from new investors to sustain the scheme. The scheme is named after Charles Ponzi, who became notorious for using the technique in 1920, even though he did not invent the scheme, but his operation took in so much money that it was the first to become known throughout the United States. Ponzi’s original scheme was based on the arbitrage of international reply coupons for postage stamps; however, he soon diverted investors’ money to make payments to earlier investors and himself.

Fin Mutual
Bitco Financial
Laxo Trade
Rockwel Partners
Hex Fund

The above list contains a few more websites that do rise some concerns as well, though we are not saying that they are all scams for sure, still we recommend to be careful should you decide to try them out. If you still want to try them out do so with the minimum investment amount and do not be in a hurry to invest a lot of coins! Do note that usually if somebody promises you a 2-5-10% or more daily return of investment or even more you should really be careful and that applies not only to crypto currencies.
