About "Bitcoin cash also has no place if we take into account other cryptos (Monero or Algorand)", I completely disagree. Bitcoin Cash brings a lot to the table:
- Shared history with BTC up to the fork day (August 1, 2017).
- SHA-256d mining, like BTC.
- Much increased capacity, about 20 times higher, with plans to continue scaling to order of magnitudes more.
- Very low fees (less than $0.01), with a roadmap to keep them low as usage grows.
- Reliable almost instant 0-conf for smaller-to-medium transactions, with plans to improve its security.
- Privacy improvements such as CashFusion [1].
I wish Bitcoin Cash didn't need to exist because BTC scaled, but until then I will keep using it and advising others to do so.
Other coins have low fees and privacy. Neither are unique selling points.
Why not use Algo instead of bitcoin cash? https://algorand.foundation/the-algo/algo-basics
I disagree with your comment about PoW because hashrate moves between coins. It's not impossible for hashrate to move from BTC to BCH in the future, especially if BCH adoption continues to rise.
