After all, the rewards given from Airdrop or Bounty are also not that big.
Most are still in the development stage or projects that have been successful immediately have a good market.
You can transfer USDT, BUSD, or other stablecoins to the market using a network that has low fees such as the BSC network, Matic, Optimis, Arbitrum, etc.
Suggestions for Hard wallets that I think are still good are Ledges Nano S or X, Trezor Model T or one, and Safepal S1 or X1.
Just choose, but some hardware wallets have their own advantages and disadvantages such as Ledger Nano which can extract private keys.
Research before you buy.
