Bitbase's 6% fixed USDT/USDC product locks funds for 360 days. Thirteen days left on the iPhone Duo tier
Key takeaway
Bitbase added 360-day Fixed Earn products for USDT and USDC at a 6% APY, with a minimum of just 1 USDT or 1 USDC. They come with a limited-time promotion that ends November 15 (16:00 UTC).

The promo is built for big balances
Only the first 50 users who reach a cumulative subscription threshold on 180- or 360-day USDT/USDC Fixed products get a phone. 250,000 or more earns an iPhone Duo (512 GB), and 500,000 or more earns the 1 TB model. Users are ranked by cumulative amount, and ties go to whoever qualified first. There's one device per user and 50 in total.
The lock is the real trade-off
Fixed products don't allow early redemption during the lock-up. Six percent for a year is a decent stablecoin rate, but money locked for 360 days can't be used as margin, can't buy a BTC dip, and can't chase an ETH or DOGE breakout. Bitbase also notes that the displayed rate can change with market conditions, so check the product page at the moment you subscribe.
How a trader might think about it
Treat it as a separate bucket, not as trading capital. Locking a slice of stablecoins you won't touch for a year at 6% while the rest stays liquid for SOL, XRP or BTC setups is a reasonable split. Locking working margin to chase a phone is not, because you'd be giving up a year of flexibility for a prize capped at 50 winners.
Subscriptions go through Finance, then Simple Earn, then Fixed on the app or website.
Would you lock stablecoins for a full year at 6%, or does the lack of early redemption rule it out for you?
