It's advisable to have a stablecoin backed by something valuable, so that If for some strange reasons it loses its peg investors can always get back the something it's backed by, or the stablecoin can automatically or manually peg back to fiat like USD as long as there is sufficient amount of backed asset.
Better to use native stablecoin that depends on strong security of its decentralized system which is basically system supervised or built by technically and morally sound members/member with strong influence over the system security.

*Bitcoin "tops out" or stops moving up if nothing strong or reasonable enough can push up further. We're temporarily in that period until there is something good, positive or strong enough to push it up. October depends on this factor too.
