You know, even with «below 40sat/byte» it is still expensive. I remember times when 1-2sat/byte was enough to get your Bitcoin in couple of hours. Now, it probably gonna wait months or transaction will be thrown away from pool. For me, paying not much than a dollar is acceptable price for a transaction in Bitcoin. From the beginning it was announced that it is cheap and anonymous alternative to money transactions. Now it is no longer cheap, and we are about to lose anonymity.
