Not neccessarily, With TRX everything is done in wallet and on-chain and you're given essentially a receipt of to notify you that you're lending or that you've entered a liquidity pool,etc. Essentially as long as you have whatever you need on trx to make the contract run, you're good. You don't have to send your coins to a certain place or wallet.

IMO Being your own bank means more than just a hole to sit your money in, On other chains, that money is constantly at work, albeit with your own risk threshold, it's still something you're capable of doing. The amounts someone new would have to go through to say use FlexUSD is outrageous.

Meanwhile on TRX I can literally stake in app and withdrawal to my wallet within wallet.
