JustLend fees are high because the platform requires a certain amount of energy to operate. This energy is usually taken from the TRX tokens of the users. This can be a costly process and can quickly deplete the tokens of users if they are not careful. To avoid this, users can rent energy from exchanges like Tokengoodies.com/trade, TRONpulse.io/energypool, TRONnrg.com or use bots like @TRON_energy_bot, @BRUTUS_energy_bot and @TRXEnergyMarket_bot. Alternatively, users can also buy energy from the discount offered by TOKEN GOODIES or #buyenergy. Renting energy from Tron NRG is also an option as it is much cheaper than paying fees.
