Justin is not unaffected. but the market doesn't really trust him anymore. the market will be like that for TRX. but if there is an update that could change the market view of TRON I think there will be a possibility that there is a project that has a good price at a low cost. and that is what the market needs today.
Honestly I do not get why people didn't see that coming way before it even started. Don't get me wrong I like tron when I need to send money to somewhere, I can use it for an insant, like take the money I have in the exchange, turn it into tron and send it, maybe 1 minute at tops, and I would not think about owning Tron more than that, no way I would get it. Why? Because exactly the reason you said, Justin Sun.
Dude is basically all around Tron and gave himself an insane amount of money from very early days and that basically resulted with him being in charge of a coin, so that means if he wants to change something in Tron he can do that and people can't argue against it, when one person has that much power over a coin, that is centralization and I would never put my money into something that has such a huge centralization, I will only invest into decentralized coins.
