Understanding Bitcoins and coming Hashgraph

This is an excellent video to help non technical people understanding bitcoin. After watching this I am more certain than ever that Bitcoin has a limited future. Hashgraph looks to be the future because it claims to solve the electricity drain problem, the transaction delay problem, the network bandwidth problem, the ledger storage problem, the super computer processing problem and is the ultimate solution to solving the Byzantine General's problem. The possible future I see for bitcoin is in wealth storage only. https://youtu.be/SF362xxcfdk
