Bitcoin have a huge value now of 2700$ and i don't see it going any higher (not on a astronomic way atleast)
Explain this line why you said that? We will see bitcoin price is at 4k$ to 5k$ in 2018. Do you know that bitcoin drop from 3000$ few months back?
Well everybody know that bitcoin is a good investment and it's price will surely increase in near future and adaptability will also increases. But in my opinion $5k for 1 BTC is still unimaginable. Although the bitcoin price was gone to $3000 but still $5k is huge dude $4k is still considerable.
