Thanks! That would mean that Ripple is really a Bitcoin contender (having even more volume) and its market cap maybe isn't inflated. Ripple, however, is a different system than Bitcoin and has a completely different trust model as other cryptocurrencies. I admit that I never really investigated it in depth and I still struggle to understand what all the "ledgers" are ...
So for me the rational strategy is simply to believe your numbers.
We could then update the conclusion as "only Ripple and Ethereum are really used."
Do you know if the same problem applies to Stellar as well?
Edit - Important: I have still not updated the table because I looked at
your source and there are two interesting numbers:
payment_count: 1210 (that's probably what I had counted because it's close to my estimation)
transaction_count: 43569
What is the difference here? What are "transactions" that are not payments?
Edit2: I think I figured it out: Transactions can be "payments", but also "created offers of an exchange", "canceled offers" (these two are the most common), "trust set", "account set" and "set regular key". The problem is if we wanted to compare them with Bitcoin, we would have to differentiate between "Bitcoin payment transactions" and "Bitcoin non-payment transactions" (e.g. OP_RETURN transactions like Counterparty or Factom txs). For now, what I'll do is to include both numbers in the table, but as in Bitcoin most transactions are definitively payments, then we can safely conclude that
Bitcoin is used much more for payments than Ripple.
to correctly evaluate it you should use the number of transactions then and today, i.e. evaluate the change in the number of transactions, not their absolute readings as of today.
Yep, you're right, a historical comparation would be even more insightful. That's a second step I plan to do. Also to be more exact I would like to compare the daily transaction amount and not a small timeframe like I did here; for that I need charts (like the one Sukrim provided for Ripple). But for now my goal was to get a rough absolute number, to get the order of magnitude of the differences between BTC and alts.
I think a timeframe in mid-December (not too close to the holidays) would be a good point to compare to today because in these times the altcoin bubble started (with Dash and some others) and also Bitcoin blocks wern't as full as today then. Let's see. Maybe next week I'll have time for it.
@talkbitcoin: This seems also to be a good answer for you.
I would be interested to see an approximation (likely the best that you could do with all the price volatilities) of DOLLAR volume. If BTC trx volume is that dominant, I would guess that $-volume of BTC trx would be even higher than your figures.
The stat I was interested in is the "number of transactions", it's not the transaction volume measured in BTC currency units. This would be another interesting comparation, however. I'll look at it if I have time.
