What future do we really hope for altcoins without bitcoin?
I think a few altcoins will survive without Bitcoin but sure it will create some chaos if ever Bitcoin dies which I think will not happen, not even in a decade from now. I don't think it will dried up if it's on spot, maybe you've decided to try futures market without some knowledge behind it, that's too risky to take. Lesson learn try spot market and hold those coins/tokens, you have the best position now for the next bull market.
if bitcoin suddenly collapsing i have firm believe that the other altcoin also will collapse. why? simple, its because bitcoin is like the brand of cryptocurrency, its like the reason why people invest in the first place.
when bitcoin is collapsing, everyone would lose trust in other altcoin fearing that it will also collapse, remember the ftx collapse? quite literally any coin that was previously backed and invested by ftx heavily hardly could rise nowadays because people already don't believe these coins anymore.
therefore if bitcoin collapsing, every coin will at least lose 90% of its value until eventually many abandoned them.
