I don't know what will happen to Luna or UST in the future although I also feel sure it won't get any better. But I personally have put $250 in there just to profit from the price volatility. Hopefully I can make a profit, but of course I'm trying to convince myself that $250 isn't going to be $2500 any time soon. Even if I have to fail, it's already considered a loss this year. LOL
That really depends when you bought LUNA; if you bought it when price was $0.01, then I think that you can forget about the investemnt, but if you bought it around the current price, then you could maybe end up in profit as there will probably be few more pump&dump cycles before it gets delisted/forked/whatever
I'm not going to do anything [invest or trade] other than just maybe hearing that UST and Luna will eventually become shitcoin in the near future.
It was shitcoin long before this happened, but many were blinded by their marketcap, volume and whatnot while in reality all Terra had to offer is 20% APY on stablecoin and that was the only reason why anyone used it. More than 70% of all UST was locked in Anchor, meaning this was nothing but a ponzi scheme that had to eventually fall apart and their "inventive" stablecoin mechanism just sped up the process.
