We have never really discussed this but these are spam transactions. I think I’ve posted articles about them but these are trying to overload the blockchain.
These are on the LTC blockchain but these are multiple $.50 transactions. There is no conceivable reason why this same amount would appear in this frequency on GDAX. In the 1 in a million chance this couple happen in the open blockchain, where somewhere at multiple places in the world, people were making micro transactions. However in an exchange environment there is absolutely no reason.
I posted an article a month ago maybe about spam and this is the same thing. It’s a artificial clogging of the blockchain network. It’s all politics and you could be miners. The miners can make all these transactions but if they are mining the blocks and keeping the fees they charge themselves they don’t lose any money. They gain support for SegWit2X and in the end can charge higher fees, which means more profit.
This is such a complicated situation but this is physical(virtual) proof that the spamming that is happening on BTC is also on the LTC network.
