For reference, [this](https://github.com/polkadot-fellows/runtimes/pull/131) is the PR that tweaks the ED on system chains, which is part of [the 1.1 release](https://github.com/polkadot-fellows/runtimes/releases/tag/v1.1.0)

**Update: Recommend rejecting this proposal. I will make a new one to go with the Asset Hub upgrade that actually updates the Existential Deposit. See [this PR](https://github.com/polkadot-fellows/runtimes/pull/158) for more details.**

This referendum is related to the reduction of existential deposit on Asset Hubs.

When you pay fees in `sufficient` assets, the system still calculates the base transaction fee in DOT. It converts it to the asset fee amount using the ratio of minimum balances. So:

```
fee_in_dot * asset_min_balance / dot_existential_deposit
```

So, if you reduce the DOT ED by a factor of 10, you also increase fees in sufficient assets by a factor of 10 (Asset Conversion, coming soon, to avoid all this).

This proposal reduces the minimum balance requirement for all sufficient assets (USDT, USDC, and KSM) by a factor of 10, preserving the ratio. There is also a fourth call to update the metadata for bridged KSM, since that [failed when creating the asset](<122>) due to the `SafeCallFilter`.



- A proposal is suggested to change the deposit amount needed for using digital assets called Asset Hubs.
- It is recommended to reject this proposal and create a new one with improvements.
- The plan involves reducing the minimum balance required for certain assets like USDT and USDC by ten times.
- If the DOT deposit decreases, it will cause fees to be higher for those assets.
- There is also a plan to fix an issue with KSM assets that didn't work correctly before.
