Galaxy Dgital Trading co-head claims that Etherium will flip btc in 3 years . He claims that people will realise the power of smart contracts they will choose to invest in eth instead of btc and with eth moving to 2.0 proof of stake it will boost eth's price. I don't think it will happen in 3 years because bitcoin his still the most reliable and secure coin to invest in. There are lots of people who don't care about smart contracts and defi so they will stick with btc as best crypto investment. Smart contracts can get hacked and this happened many times where people's money got stolen.
