I have SmartChain BNB in my Trustwallet (TW) account.
1. Is it possible to buy ETH-based crypto on TW with SmartChain BNB. If yes, then please inform me how.
2. As I am a newbie, I want to buy ETH-based crypto for only $5.1 amount. Will it be cost-effective, as many people are saying cost will be high on ETH transactions? So I don't end up with like paying $5.1 for buying and paying $2 or $3 for transaction fees.
By the way, I want to buy DEUS FINANCE. It is also on POLYGON Chain

If I were you, I would use the Metamask wallet, because it is very convenient for DeFi platforms and supports a lot of blockchains.
In a few seconds, you can switch between different blockchains.
For security, you need to buy a hardware wallet( ledger or trezor) and work through the metamask wallet interface. Then no one will steal your money, and you will only need your seed phrase when setting up a hardware wallet.
