We have pancakeswap now that is already scaling to "infinity and beyond", BSC is compatible with ETH and is now 5 times bigger than ETH in terms of TX. Pancake swap generates more TX than whole ETH. Projects are slowly moving away from ETH or at least uses bridges to BSC to enable close to free trading for their users.
This upgrade will use "Off-Chain" scalability techniques in order to "tackle" the issues surrounding the underlying Ethereum blockchain. Faster trades and near-zero fees will make Uniswap V3 a force to reckon with.
You need to send tokens to SC (smart contract) and pay for moving tokens from SC to your wallet. Min 2 transactions. The solution is for people that are constantly trading (f.e. arbitrage traders) that will lock funds in SC and move them inside from token ot token without withdrawing to wallet. It may lower the traffic , maybe lower whole ETH fees a bit but it will not be free trading for everyone unless gas price will be 0 - impossible.
60$? only if we will continue current bubble cycle. And everything will grow like crazy. I cant imagine bitcoin and whole market to go down for months while a simple swap pumps to $30 Bilion marketcap.
