Hi guys,i just wanna knows that why the transaction fee for bitcoins is increasing everyday.Some days before i send bitcoin to a trader the fee was 0.0005btc but yesterday i repeat the
same transaction same amount then the fee was 0.0006 btc.
Please correct me if i am posted in wrong section.

If you are using ETH aside btc, you will experiencing the dynamic transaction fee in ethereum network ( gas fee ).
The fee amount will depends on the network congestion. If there are many transactions waiting to be processed, then the fee will go higher.
I think it will be the same for bitcoin network as well, not everyday is increasing.
