bitcoin hold several around 7 transaction per second
the ethereum blockchain currently supports roughly 15 transactions per second
nano is better but
compare to
the 45,000 processed by Visa.\/
Bitcoin can hold 7 transactions per second,but what about the offchain/sidechain solutions that are built over the bitcoin blockchain,like Lightning Network?
For me,scalability isn't such a big deal.Decentralization and security are more important that the transaction speed or volume.
