I normally don’t write reviews like this, but I feel like I need to share my experience because I don’t want someone else to make the same mistake I did.

At first, everything with Koinvex seemed fine. I was able to buy USDT and make a few smaller transactions without any obvious problems. That gave me confidence in the platform and made me believe that I was dealing with a legitimate service. Looking back, those initial transactions were probably the reason I felt comfortable enough to put more money in.

The problems started when I increased the amount I had invested. Suddenly, withdrawing my money was no longer straightforward. I was told that my account had been upgraded to “Gold” and that I needed to have at least 30,000 USDT before I could withdraw. This was never something I expected when I initially deposited my money.

Then things became even more stressful. I was told that if I didn't meet the requirement within a certain timeframe, I could be charged a 2,000 USDT penalty. At that point I was already worried about the money I had deposited, and the additional requirements only made the situation worse.

What I find especially disturbing is that I was asked to make additional payments in order to supposedly unlock or withdraw my funds. I made the mistake of believing that these payments were necessary. Unfortunately, even after doing what I was asked, I still couldn't access my money.

That was the moment I started seriously questioning the whole platform.

There are several things that, in hindsight, I wish I had checked before depositing anything: the lack of clear Terms and Conditions, limited contact information, questionable social media links, and the lack of transparent information about the legal or registered trading name behind the platform.

If you're considering using Koinvex, please stop and do your own research first. Don't simply rely on the fact that small transactions appear to work. Ask yourself what happens when you try to withdraw a large amount, who legally operates the platform, and whether the company and its terms can actually be independently verified.

And please be especially careful if you're ever told that you need to send MORE money before you're allowed to withdraw the money you already have in your account. I wish I had recognized that warning sign earlier.

I'm posting this because I genuinely don't want anyone else to lose money the way I did. My experience with Koinvex has been extremely stressful and disappointing, and based on what happened to me, I would personally stay away from the platform.

I wish I had never trusted COIZO platform. I initially deposited 7,500 USDC after speaking with one of their ‘account managers’. They showed me consistent profits and encouraged me to invest more. Eventually, my dashboard showed a balance of nearly 21,000 USDC. When I requested a withdrawal, they suddenly told me I had to pay a 3,500 USDC tax before they could release the funds. I paid because I was desperate to get my money back, but the withdrawal was still rejected. A few days later, my account was suspended and the person who had been contacting me stopped responding. I lost both my original deposit and the additional money they convinced me to send. This was a very expensive lesson.

Please think twice before investing with Koinvex. Based on my experience, I would strongly advise anyone to stay away from this platform. I deposited my money believing I would be able to withdraw it when needed, but things changed completely once I requested a withdrawal.

Instead of processing my withdrawal, I was told that I needed to make an additional payment as a supposed fee or commission before my funds could be released. Unfortunately, I made the mistake of paying this additional amount because I genuinely believed it was necessary to get my money back. Even after making that payment, I still wasn’t able to withdraw my funds from koinvex.com

After that, communication became extremely difficult, and I was left waiting without a clear solution. The whole experience was incredibly stressful and left me feeling like I had been taken advantage of.

Please be very careful and do your own research before depositing any money. If a platform asks you to send additional money in order to release or withdraw your existing funds, I would strongly recommend stopping and verifying everything independently before making another payment.

Deposited 2,500 USDT and everything looked fine at first. My balance supposedly grew to over 8,000 USDT, but when I tried to withdraw, they demanded another 1,200 USDT as a ‘verification fee’. I refused, and my account was locked. Lost my money. Avoid this company

At first, everything was perfect. I deposited 5,000 USDC, and a "consultant" helped me execute trades. Within two weeks, the platform showed a profit of 13,000 USDC. When I tried to withdraw the money, the nightmare began. They told me I first had to pay a "commission fee" of 2,000 USDC from my personal account, claiming I couldn't withdraw directly from the profits. I paid it, and now they’ve permanently blocked my account, and no one answers the phone anymore. They are thieves—they stole all my savings!
