Hi guys! Just joined to share my research.
Being from Estonia, a tiny former soviet block country, now an IT haven where Polybius and Hashcoins are registered in, I know which sources to check. The Polybius.io webpage is registered to Polybius Foundation OÜ, a company that doesn't have much information on the register at the moment, but It was just registered 4 months ago. Source:

Hashcoins has 14 employees, a yearly FIAT turnover of 153 525.00 EUR (period 01/12/2016 - 28/02/2017) and has payed a total of 38973.54 in state and payroll taxes in Q1 of 2017. Admittedly, that doesn't seem huge, but given that the median monthly wage here is ~720 and that they probably don't convert the majority of their assets to FIAT - not too shabby. The company also has a 5/5 star rating on innovation, personnel performance, social responsibility and quality of product/service. Source:

Looking at the companies long term goals and the whitepaper it seems obvious to me that IF they succeed in their endeavors they will become game changers as the system would bring a lot of new funds to the crypto scene. At least if it all goes belly up, I'll know which bus to hop on and which doors to bang on

After all the talk about Hashcoins being a scam I fail to see how the company can still be functional and successful while giving employment to 14 people... thinking of calling them up to see if they are interested in an interview.
You should ALWAYS do your own research and NEVER - EVER blindly invest money you cant afford to loose, but if you appreciate the tiny tip I just gave you, I wouldn't mind being tipped myself

There is an opinion that in Estonia not everyone can succeed, that there is a glass ceiling that does not allow to break up. The "AK +" reporter Konstantin Sviridovsky in his story, aired on ETV + on April 16, tells of the dizzying success of five friends who managed to destroy this stereotype. The company Hashcoins today is one of the three largest enterprises in the field of crypto-currency production.
The company appeared in 2013, and then no one thought of creating a bank. At that moment a group of enthusiastic friends saw the future in the crypto currency, in the so-called bitcoins. It was interesting for them to collect special computers that, similar to printing machines, obtained virtual money.
At that time there were only 5 people working in the company. At night they gathered in the office, developed new schemes for composing the components, so that computers for mining bitcoins worked long and reliably. Then the company decided to create hundreds of such computers and lease their production facilities, since there were many who wanted to produce bitcoins, but they did not have money for expensive equipment. And pretty quickly, the customer base has grown to an incredible size. And today, as already mentioned, Hashcoins is one of the three largest companies in the world to provide this kind of services.
