Every time is a good time to invest, what you should do is watch what type of investment you join in crypto currency today so you can avoid the fake projects. What to do after checking whitepaper and token product? check the token address basic information with @CheckMyTokenBot on telegram. That way you are able to identify all about the token contract
I don't know if you created that bot and you are now shilling it here but even if not, I think people are still going be cautious with that because they know that telegram is a den of scammers. It is still possible for us to tell if the token address is legit or not even without going to telegram but we will only search the real token and then compare it on what we have found.
Every time is not a good time to invest because not all times the value of the coins are low but sometimes their value are at their highest peak. Now tell me if you have tried investing during that scenario? I believe you haven't because you are afraid of what can happen next.
