Not a very big value compared to todays standards of financial industry, but the growth rate has been unprecedented. The reasons are quite fundamental though, distributed trust instead of central control, and this has given rise to a network effect which is a catalyst for the ecosystem.
There has been a shift in the way world looks at financial services, the idea of financial democracy, free from central control, mistrust and focus on cost economics is well and alive.
* The #bitcoin blockchain was probably the first real proof of concept that decentralized finance can work and challenge the world order.
* The idea of #DeFi is not exciting because of the fact that it can be used to build better analog financial services that we already use, instead the real revolution will be driven by the fact that now there are new building blocks, new problems which will give rise to entirely new unique use cases.
* This will bring new challenges as well, but they probably will be worth solving to achieve the new world order.
The next #bigtech is yet to be built, and in all likeliness it will be build on #web3.
