Is it possible value of other digital currency will high than Bitcoin.
People are request to talk about it.
if you are talking about specific value then check market Because this is much Expensive compared to the price of Bitcoin
https://coinmarketcap.com/currencies/yearn-finance/But i think what you are saying here is the market Capitalization?
if that so then the answer is "Not for Now" or anytime soon because even the Highest growth last month in which the DEFI did not even get closer to 20% of the totality of Bitcoin cap,so we won't be seeing that in the next couple of years.
I think the OP was referring to value in terms of price and not in market capitalization, people view the value of most coin base on the current price in which they are being traded, as it is yearn.finance seem to be more "pricey" than btc (which to me is the right word to use than "value")
Yearn.finance can be pricey than btc because the developers make the supply to be very limited but that does not make it valuable than btc, it is one thing to have a high price and it is another thing entirely to have a real value that have lasted a decade.
