Sorry but maybe you misunderstood something. 5k is just our lowest package but it is still full of functionality. You can use higher development packages with more features like 10k or 30k packages.
Yea, no.
You seem to misunderstand. I am warning any potential customer to not fall for this.
There are basically 2 options:
1) You are malicious and have backdoors or vulnerabilities built in to exploit it later on or
2) You think your software is secure, but it is full of vulnerabilities which allows an attacker to steal funds later on.
There is nothing else which can happen with your "packages".
Even your "30k package" is way to cheap, since it is not about the features but the security. It is either a scam or bad quality.
