# How to purchase USDT

To participate in any projects on our platform, you will need the stablecoin USDT, and you must have it deposited on the network where the presale is taking place.

Please refer to the [Networks](/bipzy-crypto-platform/investing/networks.md) section to identify the appropriate network for the presale.

It is important to note that on each network, you will also need the native currency to pay for transaction fees. Here are the details for each network:

* **Ethereum:** Pay fees with ETH 
* **Arbitrum:** Pay fees with ETH (not with ARB, since is a L2 of Ethereum)
* **Polygon:** Pay fees with MATIC
* **BSC:** Pay fees with BNB

You can acquire both USDT and these cryptocurrencies to pay for the network fees on any centralized exchange (CEX) such as Binance, Kucoin, Bybit, or Coinbase... and then withdraw them directly to your wallet ([Metamask](https://chromewebstore.google.com/detail/metamask/nkbihfbeogaeaoehlefnkodbefgpgknn?hl=es) or [Rabby](https://chromewebstore.google.com/detail/rabby-wallet/acmacodkjbdgmoleebolmdjonilkdbch?hl=es)).

If you prefer not to use a CEX, you can also use our page, which features a widget from Changelly, a leading provider for purchasing crypto with a bank card.

Here is a video that explains the process:
