2. FYI, there is no way Bitcoin does 3k transactions per second. Are you referring to 3,000 the number or something else?
Not the guy you replied to, but I thought that I would point out that it doesn't look like his "3tx/sec" has a "k", so you might have misread because of the spacing or lack thereof. So yeah, he meant 3 transactions per second lol.
First of all,I do not agree on the efficiency of cryptocurrency especially Bitcoin.Credit cards,in this case Visa do process 2k tx/sec while Bitcoin 3tx/sec,that's a huge difference.So yeah I think Bitcoin is really not efficient in terms of transacting.
As for the article itself, wow that's long. I would have loved to see a discussion about crypto's learning curve and user experience in the practicality section though, because that seems to be a pretty big factor among self-declared non-techies. I personally think it's really easy, but that it should be tackled when discussing crypto's practicality vs. other options. Some people may find setting up a proper wallet be more daunting than simply filling out paper work to their banks, for example.
Overall I can kind of sense that you're a bit biased towards crypto, but it's an informative write up nonetheless. Good work!
