Time to buy.
Hold until Testnet.
There is no reason to stop holding after testnet.
Generally, the real market price will come out when the mainnet releases.
I think he meant than buy back before mainnet?
I would rather buy now and sell just before mainnet release. Usually, hype around a release overprices the coins. It hardly ever happens that all expectations are met and the price holds.
FOMO is real, especially just before a release.
