When looking at the last hours of bitcoin cash (BCH/BCC) transactions I saw a massive increase in low(or no)-fee transactions:
Usually the graph looks similar to the BTC case (see below), just without the backlog of unconfirmed transactions.
Is anything known who did this and why? Is it just to test out if BCH is able to support high transactions volume without problems (fortunately it seems so, with ~20k transactions per block) or does somebody have malicious intentions and is trying to stall the BCH network?
Have people done similar things with BTC in the past?
