At least next year, Bitcoin should finally solve its overripe scalability problem, which still amounts to seven transactions per second. If he does not solve this problem, then he may be in big trouble. True, it remains to be seen how the current fall for Bitcoin will end, in general, its popularity is falling.
It may shock you, but Bitcoin's transaction throughput currently is like 3-4 per second. You shouldn't pay attention to theoretical transaction throughput per second figures, because real world usage easily nullifies these figures. What matters is transaction throughput per second based on how much block space is being used.
If we look at the top 6, then this is how things currently look;
1- EOS 16-17 transactions per second.
2- Ethereum 6-7 transactions per second.
3- XRP 4-5 transactions per second.
4- Bitcoin 3-4 transactions per second.
5- Ethereum Classic 0.55 transactions per second.
6- Litecoin 0.28 transactions per second.
