+NOTE:
+
+# Compare this benchmark to go-ethereum/common.Address utils
+- go-ethereum/common.HexToAddress speed: 45 ns/op, 48 B/op, 1 allocs/op
+- go-ethereum/common.IsHexAddress speed: 25 ns/op, 0 B/op, 0 allocs/op
+
+It's slower than go-ethereum/common.Address utils because ethereum wallet address is Hex string 20 bytes,
+but Bitcoin has many types of address and each type has complex algorithm to solve (can't solve and validate address type directly from address string)

+			- Will be okay returning excessive UTXOs (say we predict we need 10K satoshis, but actually we only need 5K satoshis, then we will return UTXOs enough for 10K satoshis)
+		- And then we:
+			- Construct the actual PSBT, then select UTXOs to use accordingly,
+			- If the user's balance is not enough, then we will return an error,
