confirmation time has increased and with Bitcoin network again , also fee has rose high , looks network congestion after this rally
As the price of the btc is increasing so is the network fee is being increased. I do not know what will happen when in coming years btc value reaches 10000$. If this is how the fees is being increased then I think there are today so many other coins which have a good potential to serve the people their needs they will switch to it with less price and lesser fees with quick confirmation.
Yes that's correct, because of the current btc price which suddenly increased. Most of the exchanges also adjusted their network fees, of course they treat as a business so they can't get profits if the transactions fees would stay the same with bitcoins price that's high. But it will be stable once bitcoins price will be stable again soon.
