The value of Bitcoin lies in the trust of investors!
The existence of Bitcoin is reasonable, but for me, it always exists like gold. It does serve as a currency in a certain historical period in the past. Bitcoin should compete with French currency!
Bitcoin is essentially a gold draped in a high-tech coat!
Bitcoin for me will always have a value cause there will be always investors whose want to put their money into this project, thanks to that situation this coin can't lose its value.
