> Unclear if you're talking about Bitcoin specifically or cryptocurrencies in general, but there are cryptocurrencies that handle transactions quickly and at scale in a secure and decentralized manner. Algorand is one of those, but there are plenty of others out there that fits the requirements.

In general. Every time I heard a cryptocurrency claiming to be fast and decentralized, it either didn't live up to performance expectations or there were major caveats to decentralization. I can't comment on Algorand specifically as I gave up on following crypto.
