How to Buy Best Patent (BPT)
Every exchange we track that lists BPT, what the buy costs, and what it costs to take BPT with you afterwards.
2 of the exchanges we track list BPT, and 2 of those accept fiat, so you can buy it without holding crypto first. The cheapest place to place the order is Gate at $1.00 on a $1,000 market buy. It is also the cheapest once the withdrawal fee is added — $1.35 to buy $1,000 of BPT and move it to your own wallet. Every exchange sends BPT over BNB Smart Chain (BEP20), so there is no network to get wrong. 1 of them has BPT withdrawals paused right now — you can buy there, but you cannot take the coin with you until it reopens.

Where to buy BPT
All-in cost is the trading fee on a $1,000 market buy plus the cheapest fee that exchange charges to withdraw BPT. It is the number the exchange’s own “how to buy” page never shows you, and it reorders the table more often than not. The coins column is how many assets each exchange lists in total, from our own sync — not the figure CoinMarketCap prints.

Buying BPT step by step
- Pick a venue from the table. For a coin this size the choice is usually short — 2 exchanges list BPT at all, and the table already shows what you will pay to leave as well as to buy.
- Fund the account. 2 of those exchanges take fiat, 2 of them by card. Card is fastest and dearest; a bank transfer costs a fraction of it. Depositing a stablecoin you already hold is free on almost every exchange here.
- Place the order. A market order pays the taker fee in the table; a limit order that rests on the book pays the lower maker fee. On a thinly traded coin the spread costs more than either, so a limit order is worth the wait.
- Decide whether to move it. Leaving BPT on the exchange is free but custodial. Moving it to a wallet that supports it costs one withdrawal fee, from $0.3506 — send a small test amount first, and match the network on both sides.
How to buy BPT — FAQ
Where can I buy Best Patent (BPT)?
On 2 exchanges we track: Gate, KuCoin. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw BPT.
What is the cheapest way to buy BPT?
Gate, at $1.35 to buy $1,000 of BPT and withdraw it — $1.00 in trading fee plus $0.3506 to move it out over BNB Smart Chain (BEP20). If you are leaving the coin on the exchange, only the first half applies and a different venue may win. Paying by card adds the card processor's charge on top of both, typically 1.8–4%.
Can I buy BPT with a credit card?
Indirectly, yes. 2 of the exchanges listing BPT accept a card (Gate, KuCoin), but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for BPT on the same exchange. That means two fees: the card charge, then the trading fee in the table.
Do I have to pay a fee to withdraw BPT?
Yes, and it is worth checking before you choose where to buy. It is a flat amount of BPT, set by each exchange per network, so it does not scale with the size of your purchase — the cheapest in the table is $0.3506 on Gate. Our full BPT withdrawal fee table compares every exchange and every network.
Is it safe to leave BPT on the exchange?
It is a custody choice, not a safety switch. While the coin sits there the exchange holds the keys: convenient, recoverable if you lose your password, and dependent on the exchange staying solvent and keeping withdrawals open. Moving it to a wallet you control removes that dependency and costs one withdrawal fee — from $0.3506 for BPT. For a trading balance, staying put is reasonable; for a long hold, most people move.
Exchange coverage for BPT comes from each exchange’s own deposit and withdrawal endpoints (last sync 2026-08-29 00:53 UTC); trading fees are the published base tier, no volume discount applied (verified 2026-08-28).
