Transactions drop from 500,000 to 100,000 on 2019-06-28 instantly… Right.. that’s not a bot..
Every chain that has 0 transaction cost has fake volume, fake USD sent value, and in general transactions generated by a script or bot.. Why? because it’s free… to do it. It costs 0.
If you want to gauge how valuable a chain is you can only weigh the transactions against the cost to do them.
