Bitcoin was a joyride for early investors, as the cryptocurrency surged from less than $100 earlier in the decade to more than $19,000 last December. However, the digital coin has fallen to around $7,500 since then as the hype and speculation around it seem to have peaked. At the same time, Google searches for "bitcoin" have also dropped sharply since December.While crypto fans may be unfazed, the majority of the market seems to have moved on.
