I think one of the take home messages here might be that due to this difference in effort and other factors having to do with privacy and the fungiblity of Bitcoin in general: do not reuse Bitcoin addresses. Bitcoin addresses should be used exactly twice: once to fund them and once to spend them - then never used again.
There's plenty of addresses with hundreds or even thousands of transactions on them, so what you're saying is that bitcoin isn't secure enough and those addresses are more at risk?
bitcoin address design for use one time is correct
I remember first time don't know about bitcoin I look at bitcoin address I think may be bitcoin is cashless copy idea from RFID code, RFID wristband for use on event and activity ticket payment (cashless) by use one time and thrown away , and it use same thing RFID is better and Easy use bitcoin address is not easy to use require to print out and not easy to scan (I think bitcoin is cashless same RFID cashless system)
