In my opinion, Gym Network is not a scam. The entire team behind GymNetwork is very transparent, has a digital footprint, shows up in regular zoom calls and is available to answer any question.
In addition, the project runs decentrally and via smart contracts and is therefore not that easy to manipulate. CertiK has verified that the gym is programmed as they state. The most renowned audit company in the crypto sector and can also be read. The CertiK certificate also confirms the security and that there are no major security gaps in the programming.
Gym Network is decentralized and therefore does not require KYC. In addition, the invested funds are not with Gym at all, but with Alpaka Finance. One of the largest decentralized crypto exchanges ever. So that from my point of view the chance of a scam at Gym or the total loss of the investment is very low.
