Ten years in, nobody has come up with a use for blockchain
Kai Stinchcombe

For several years, I was using Bitcoin to send money overseas. The savings were incredible, running from 10–20% compared to Western Union. The number of transactions per second has been fixed with Bitcoin 2.0 (also known as Bitcoin Cash) although due to a misinformation campaign by Blockstream, most people haven’t moved over to it yet. Bitcoin 2.0 (Bitcoin Cash) also fixes the energy cost issue by allowing many more transactions per computer hash operation. It currently uses about 20% as much power as Bitcoin 1.0 (Bitcoin Core) while making blocks up to 8 times as big, so is about 40 times as efficient. This efficiency will go up as the blocks are increased in size.
