We have banks that are paying us low interest. And over the top we have many nations being target with the US based sanctions. And it is necessary to replace the USD in the upcoming times. So how would you reduce your reliance while still using them? There is a way. You can keep them locked with the drift protocol and then earn the interest. 

So say you have like 200 USD and want to earn the yield on the stable coin like USDC or the USDT. And you want to use the drift protocol. Find the pair for the yield and then you can lock your asset. This would help you attach the collateral and earn the yield in the process. 

Many other finance protocols are making use of the drift too. This makes multiple investment and spreading risk easier as well. 

You can then later trade the yield and get converted into the coin of your choice. So such protocols are handy. You can also have such similar programs with most of the wallets and the exchanges. But you are kind of stuck with the KYC. So you risk a little with such protocols as nothing is secure in these times. And so you risk little and take some rewards. 

I would never invest 1k or 2K into this. But little 250 or so is good enough to invest and take out after short lock. They can be sustainable in that order. But yeah sooner or later your banks would be offering you that collateral based yield. No longer keeping foreign currency for free into their account. 

Let's see where the future of finance is going, definitely it is moving away from the USD for sure.
