hello guys
how are you ?
Im fine and what about you?

have a nice time
I have a question about altcoin and that projects !
how to check and trust in altcoin and that projects ?
for example
https://www.certik.org/ is good idea to check project ?
That site being used to check whether the code that used by the project already fully audited and there was no back door that implemented by the developers or not. That's a good idea to check or verifying the contract was fully audited and there was no shady things already put by the developers to the smartcontract.
have you seen site, online platform or applications like
https://www.certik.org/ to check and verify altcoin projects ?
Yes i have seen that. there are some audit platforms other than certik like hacken and chain security. It's good to see that you're aware about this.
can you help me ?
I have been answering your question and you can see my answer above.
