Thank you for the kind words, and for reading so carefully. You got almost all of it right. Two small corrections:

The 0.08% fee is for the LASSECASH:HBD hop on the native pool. The HBD:BTC hop is MAGI's own pool, with its own fee.
ETH and USDC depend on MAGI's timeline, not mine, so I won't promise a date.
Your questions:

Key burn: 10 October was the plan. In early October, while I still had the key, we found a bug that blocked payout of the large early mints. Only a code update could fix it. It was fixed on 4 October and the audit has been green since. That changed my mind about rushing. I'm now leaning toward keeping the key well into next year and testing over a long period, so everything is proven before it is frozen for good. People have trusted me with LasseCash since 2019, and a longer hold only makes the final burn safer. The burn height will be announced before it happens. Until then the contract is not immutable, and every code update is public and waits 48 hours before it takes effect.

Swap: the LasseCash core pool at lassecash.com/pool is the home of LASSECASH, and it works today. Trading costs 0%, a fee the code makes impossible to raise. Liquidity providers are paid from 25% of all new LASSECASH, so I think it's the best place to be. Altera is where you swap LASSECASH to Bitcoin directly, until I add that to lassecash.com as well. That part is just a matter of time, since I'm building on many things at once. When it comes, the natural route is the 0% core pool first, then MAGI's HBD → BTC pool.

Fresh numbers, read from the chain today (6 Nov), paid in LASSECASH:

Liquidity in the core pool: about 122% APY for new liquidity, rising toward about 232% as the loyalty bonus builds over 90 days.
Minting: about 116% APY for a small short mint, up to about 261% for 50,000+ locked 3 years.
These move both ways with what users do, so they are a snapshot, not a promise.

About @holovision.cash: he has been attacking and trolling me for many years now, I've lost count of how many. I won't answer it point by point. LasseCash is public code on a public chain, so judge it by that.
