How possible can bitcoins reach even 15,000 before the year come to an end? Bitcoins price can't reach 60,000 USD by 2020 if the trend of which bitcoins is going don't change.
You can expect the unexpected with bitcoin market, have you ever expected that the price will surge up to $20,000 last December? It looks impossible to see this coming for this year but everything can turn the tables down if this happens, great if it didn't we still got another year to expect - that's it.
