Well, it seems like the Mary hard fork of ADA (Cardano) has a big effect on its current price and status,
It seems true, im also waiting for the result from the hardfork and if the defi can start to use ada and there will be a massive exodus from BNB and ethereum to the ADA. ADA will become decentralized platform for DAPPS that has a very good scalability. that should become the main point why ADA already pumped so hard.
My ada was also growing a lot too.
The big effect hasn't shown yet but there were teams already interested to use Cardano blockchain. Cardano reviews had also become very positive, its almost like they all collaborate with each other to one big conspiracy but its making the price of Cardano bigger.
Among the 3, I think Cardano will have a better solution to problems we encounter on different blockchain in term of scalability, interoperability and its POS.
