I do not think so, basically, as the block grows, the nodes may also increase, so the speed of the transaction will be fast, the transaction fee will also be greatly reduced, bitcoin will continue being the most powerful money currency virtual currency market.
No. You're seeing the wrong way.
More nodes don't equal to faster transactions and lower fees. A node is just a validator for the Bitcoin blocks and transactions.
What is making Bitcoin slower and more expensive is the lack of space in the blocks, which causes people to have to put high fees to have confirmation priority on the next few blocks.
