TOTALLY MEANINGLESS.
Why would I care how many public txs  were made at that conference?
That means were traced...
What really matters: how many new merchants are accepting BTC.

The most important measurement about Bitcoin is like: we do not know how many txs were made... is impossible.
Otherwise are not made with BTC, but with any other custodial shit that is tracing all your movements.
We should not be proud of that...
