There is no best range for everyone: around a $100 token price, $80–$125 is one example of a moderately wide band, not a forecast. Choose bounds you can accept even if the price reaches either one before you check again.
A range sets when your funds can earn swap fees
Concentrated liquidity means placing funds within a chosen price band instead of spreading them across every possible price. The pool can use your funds for swaps while its price stays inside your band, and you may earn part of the fees from those swaps.
If the price leaves the band, your position becomes inactive and stops earning swap fees until the price comes back. As the price moves toward either boundary, the balance shifts between the two tokens. At one boundary, it can become entirely one token; which token depends on the direction of the move and how the pair is quoted.
That shift is the main trade-off behind a narrow range. A narrow band concentrates more funds near the current price, but the price can leave it sooner. A wide band is more likely to stay active through a larger move, but spreads your funds across more prices.
Set the bounds from a price move you can accept
Suppose a token is trading at $100 against a stablecoin such as USDC. An example range of $80–$125 leaves room for a 20% drop or a 25% rise. Those numbers illustrate the choice; they are not a recommended range or a prediction of where the token will trade.
Now imagine the price falls to $80. Your position may then be entirely in USDC and inactive. If the price rises to $125 instead, it may be entirely in the other token. In either case, you hold a different mix from the one you started with, and fees stop until the price returns inside the band.
Before setting bounds, ask how much price movement you can leave unattended between check-ins. Look at the token’s past swings over a period that matches how long you expect to leave the position alone. Past moves cannot predict future ones, but a band narrower than the moves you see may need frequent attention.
If you settle on a band and want to provide this kind of liquidity, Byreal is a Solana DEX incubated by Bybit for token swaps and concentrated liquidity. It is one way to put your range choice into practice. Byreal’s concentrated-liquidity pools use chosen price bands, so the same active-range trade-off applies.
Check the position against the alternative
Estimate what you would hold at the lower bound, at the upper bound, and after a move beyond either one. Then ask whether you would still want those tokens at those prices. This matters because earning fees does not guarantee that your position will be worth more than simply holding the original tokens.
Also consider how often you can check the position. If you only look in a few times a year, a wide band may fit better than a tight one. If you choose a tight band, be ready to review it more often and decide whether to reset the bounds when the market moves.
Byreal can be a way to act on that decision, but the range still needs to fit your own plan. A position outside its band earns no swap fees while it is inactive, even if the pool is busy. For occasional use, choose the widest band whose end-point token balances you would be comfortable holding.
