Get amount in PGT (including multiplier)
API (temporarily): https://siewchongche.space/predictionGame/getAmountInPGT/?amountInUSD=${amountInUSD}
Get amount in BNB
API (temporarily): https://siewchongche.space/predictionGame/getAmountInBNB/?amountInUSD=${amountInUSD}

const amountOutMinForDeposit = stakingHelper.getAmountOutMinForDeposit(amountBNBToStake, 1000)
await stakingHelper.deposit(amountOutMinForDeposit, {value: amountBNBToStake})

await staking.claim()
