Bitcoin keeps going down and forecasts of a rebound don't fulfill anymore
Bitcoin will go down when last miner will stop mining it. For Bitcoin to work you only need two users. Where there were Satoshi and Hal Finney, they made it work. Satoshi by himself could not. I mean he could send coins to himself, but that would be just pointless.
I agree and aside from miners here must be sender and receiver or the masses who'll use this blockchain technology. As long as bitcoin fulfilled its purpose, a decentralized cryptocurrency then bitcoin is here to stay. As long as bitcoin is being utilized because of its flexibility, secure and fast and being decentralized more people are joining the ranks of using it.
