I'm not trying to argue that transaction capacity is the most important metric, but it's a metric you yourself mentioned as important and it's a metric I have not been able to verify for many cryptocurrencies I've looked at.

If you say "Choose proven cryptocurrencies with transactions" I am going to assume you don't mean ten transactions/day.

I do not think it is unreasonable to ask "How many people are actually transacting with this cryptocurrency?".
