The Cardano price is forecasted to reach $2.89801 by the beginning of October 2021. The expected maximum price is $3.62251, minimum price $2.46331. The Cardano price prediction for the end of the month is $2.89801, after the Alonzo Fork. But what will make it achieve $ 5 and when will it happen? Will Cardano position itself to replace Ethereum and tackle the issue of huge gas fees? 
For Cardano (ADA) to reach $5 value is possible, just a matter of time. And as you ask, can Cardano replace Ethereum and solve the huge gas fee problem?My answer is absolutely possible, but besides ADA there are many other competing networks with very cheap fees such as BNB, SOL, MATIC, DOT… This will make ADA not the only network that can be used right now. multi-blockchains, competition is inevitable.
