BTC fee spiked right before paying vendor - how do you handle it?
Yeah, I feel you — honestly, nothing worse than sitting down to finalize an order and seeing mempool fees spike right when you're about to hit send. That "couple of blocks" approach is solid, and you're right, late night (especially like 2-5 AM UTC) usually sees fees drop as traffic from Asia and Europe dies down. I'll usually open a mempool tracker or check the fee estimator on my wallet to see if the sat/vB rate is trending down. If it's dropped by even 10-20 sat/vB in the last half hour, I'll wait one more block to see if it sticks.
One thing I've learned the hard way? Never panic-pay the inflated fee. The escrow system usually gives you a window — just communicate with your vendor if you're cutting it close on the timer. Most are pretty understanding if you say "waiting for fees to drop" and they'll either hold the escrow or extend the deadline. But some vendors have a hidden fee trap: they quote a price in USD but expect you to cover the full BTC network fee on top. If you're not careful, that spike can eat into what you thought you were paying. So now I always ask upfront if the quoted price includes the miner fee or if it's separate, and I clarify whether they use a fixed fee or variable.
As for cryptocurrency fee tips, use a wallet that lets you set your own fee — Electrum, for example — and don't be afraid to go a little below the estimate if you're not in a rush. I've had transactions confirm with 1 sat/vB after 4-5 hours when the network cleared. For escrow safety, never send more than the exact amount. Some escrow platforms lock funds based on the timestamp of the transaction, so overpaying can complicate refunds if fees spike after you send. And be wary of vendors who demand payment in a very specific timeframe; that's often a red flag that they're trying to force you into paying a high fee window. Pricing context: right now we're in a period where BTC fees are averaging 30-80 sat/vB for fast confirmations, but a couple weeks ago they hit 200+ for a few hours. Just wait it out, check the mempool every 20 minutes, and you'll usually see a dip within a few hours.
