Hi guys,
The first guess is me 65k-70k USD
I guess that would be too much but some investors and even businessmen predict it to be $45k by the end of 2018. So in this part of the year where bitcoin price is still in ups and downs, it is better to invest more since the price is still low.
Bitcoin prices in the end of 2018 will increase over the first few months, but it's not just the price of it increasing that its users have increased over time, I guess its price will end at 30k by the end of 2018.
