...out of the 235,000 transactions only 90,000 are actual regular transactions. 61% of the transactions currently being mined are long chain spam transactions. So less than half of what is included in all those 1MB blocks is useless junk....
if there junk why are miners including them in blocks?
to get the fees
the TX themselve are probably all junk tho.
so junk TX are filling up blocks and thats why i have to pay a fee of 4cent or more.
