I don't see cardano that can compete binance, I think cardano will not deserve in 3rd place because binance is powerful, it has big exchange, many project team prefer binance smart chain, binance is really popular so it's really deserve in the 3rd place.
We already seen that before, XRP replaced ETH before residing at 2nd spot, now the wave for cardano is bringing this coin to third spot
by it's hard to sustained since Binance have lots of offers, BSC gained more investors.
With some good run and some new developed projects that prosper this coin will bounce back and regain that 3rd spot position again.
