Hopefully Bitcoin transaction fees won't go up again anytime soon, because the current transaction fees are high enough for me.
But seeing investor demand for Bitcoin continues to increase, there is a possibility that Bitcoin transaction fees will increase as
happened to Ethereum. The best solution by maximizing the use of the Lightning Network.
Alas, I read information that the fees for Bitcoin transactions will grow, this cannot be avoided, otherwise you will have to sacrifice security. But since bitcoin is the currency of the future, and the number of investors is increasing, the problem must be solved.
