Is it to late to invest?
It's NEVER to late.
The contract is written to provide optimal entry for each user, new or old. This is the reason the Dishes per $BNB amount changes frequently, with TVL fluctuation, to provide an even playing field for any new user coming to CZ's Kitchen and not giving the first user(s) a head-start. Also don't forget that we have an entire eco-system, that's gonna back up the Miner protocol. So it our case, it will NEVER be too late
