Yieldly... At what point do you declare a coin / token dead?

Titles says it all.

I've been following Yieldly, a token on the Algorand blockchain, since last August. I was incredibly bullish on it back then, as I was for everything to do with the Algorand ecosystem. However, after a series of missteps, bad comms, and sketchy incidents from the devs, around Dec-Feb, I lost all confidence in it.

It's down 92% YTD... Algorand is down 58% YTD.

What's more, I came to see it as emblematic of many altcoins designed to make the founders and early investors rich. It fit the classic textbook example of a token designed to be staked for more of the same token with a super high inflation rate.

I know that Yeildly is by no means unique in that way. Funny enough, it's what lead me to selling all my altcoins and going all in on the Bitcoin.

Bitcoin is down 15% YTD.

One thing I often hear people discuss is how important a the community surrounding a coin is. I think that's total bullshit. The "community" is more often then not bots, paid shills, or overly extended bagholders trying to pump the price so they can profit and get out. What gets me is that some of these people hang on to the very end.

But what are the features that tell you a coin or token is dead and not just down with a potential to recover?
