And so will be the transaction fee, am mo longer a fan of eth to say the truth, am always upset whenever I have to pay such high fee for transaction, I really do not care about their groundbreaking stuff, they should do something about high fees if they can or make the price to dump 
Unfortunately that's true. It doesn't matter how great the upcoming upgrade if the fee is as ridiculous as it is today they better fix it first and deal with the other problem after that. The fee is simply ridiculous to the point where it's not worth it to send money with ETH anymore. Situation with eth fees is already better than it was before. It will be normalized by the end of the year, i guess
Maybe but if they do nothing resolving the issue it's gonna happen again and uniswap isn't gonna go anytime soon.
