Some defense against this sort of attack needs building into Bitcoin. It cost me money waiting for my transaction to go through. I wanted to sell some of my Bitcoins at the top, and by the time my transaction got through the price had gone down, and I had to sell for less.
you solve this my increasing the fee bro, or by leaving your bitcoin into the exchange
it's a good strategy tha many do when they trade daily
it is not possible to ignore small transactions like 0.001 BTC because there is a lot of micro transactions being done with bitcoin and banning those transactions is just not possible.
this is one of strengh of bitcoin, microtransaction with visa and mastercard are not really possible
and they would cost you a fortune, here microtransaction can be free if someone want
