Gratex is still in alpha version, some script and design improvements will be made in next days. So far they are without monitors and, according to my first impressions, the team will not pay any hyip monitors or blogs, at least in this first phase of work. They obviously have experienced team of promotors, again outside usual hyip market, but inside of MLM projects. ( Yes I wrote the same for Onestart)

REVIEW

Gratex PDF presentation

Gratex, in their about us page says:
Gratex as a holding started its work in 2013 just with a small group of enthusiasts on board: they were several research scientists and three investors who believed in the technological potential of graphene. Much has changed since then. We warmly remember our very first partners and clients. Now many of them occupy key positions in their regional company offices.

TECHNICAL DETAILS
The domain is registered on 20th August 2020, and updated on 19th October, when the project was launched.
The script is well-known and good H-script. The hosting is well-known good one by Hetzner Online GMBH.
Servers are strong German cover-dns.
Since the site is still in alpha version, there are some errors in script and not finished design, but nothing so important in my opinion.

THE PLANS
There are several investment plans, but I think most of the investors from hyip market will choose the first two:

1) Autoindustry Deposit amount: $50 - $1000; Daily Profit: 2%; Deposit Term - 33 days; Deposit refund: at the end of the term.

2) Medicine Deposit amount: $1000 - $5000; Daily Profit: 3%; Deposit Term - 24 days; Deposit refund: at the end of the term.

Accruals are on calendar days.
Withdrawal timeframe is up to 3 hours in automatic mode after request.
Electronic payment processors are Perfect Money and Payeer for USD, crypto BTC, ETH.
Minimum withdrawal amount is 1$ and 0.0006 BTC or equivalent for crypto.

AFFILIATE PROGRAM
Affiliate program offers 9% in first line of referrals, and then, depending of personal deposit and structure turnover it can reach ... levels.

MY IMPRESSION
I received the info about the project today. What I like, this is another project outside classic hyip market. There is no monitors, no high refback, no insurance traps. And I made deposit one hour later after I opened the site.
