Question 1

How do I identify a Flip Knife Doppler Phase 4?

Accepted Answer

Check the pattern index on a third‑party database or in‑game inspect. Phase 4 indexes range from 418 to 617. Look for dominant blue/black color with little to no pink or green. On CSBoard, each listing displays the pattern index and phase tag, so you can filter directly with the tier selector or sort by pattern.

Question 2

What is the current market price for a Flip Knife Doppler Phase 4?

Accepted Answer

Factory New classic Phase 4 typically sells for $800 – $1,200, while Gamma Doppler Phase 4 commands $1,000 – $1,500. Minimal Wear drops the price about 10‑15%. Field‑Tested exists but is rare and cheaper. Live prices on CSBoard are anchored to Buff163, so you always see fair market value.

Question 3

Does CSBoard charge any fees on Flip Knife Doppler trades?

Accepted Answer

No. CSBoard has zero trading fees and zero commission on P2P trades. The price you see is what the seller receives, and the buyer pays exactly that amount. Only the network’s blockchain gas fee (a few cents) may apply when withdrawing USDT.

Question 4

How fast do I get paid when I sell a Flip Knife Doppler on CSBoard?

Accepted Answer

Sales complete directly through Steam trade. Once the buyer accepts, CSBoard releases USDT instantly to your connected wallet. Payouts are available on TRC20, BEP20, Solana, or TON networks — arrival times depend on the blockchain but are usually within minutes.

Question 5

Is a Gamma Doppler Phase 4 more valuable than a classic Doppler Phase 4?

Accepted Answer

Yes, typically 20‑30% more. Gamma finishes are rarer and the cyan/emerald palette is highly demanded. Both, however, follow the same phase index rules. Check current listings on CSBoard to compare exact prices.

Question 6

Can I trade my Flip Knife Phase 4 for items directly on CSBoard?

Accepted Answer

Currently CSBoard focuses on USDT‑based P2P trades, so you sell for stablecoins rather than item swaps. This eliminates the risk of declined trades or bot holds. Sellers get immediate cash‑out, and buyers can purchase the exact skin they want.
