BTC is a little above $5,000 now. Can I still buy it? Is there any chance that it would rise further before the end of the year?
In my opinion, I would say that its highly risky, but its worth a try. Bitcoin has risen significantly in the last few days, and the value might continue rising even in the next few.
Its very risky in the sense that there is the hard fork coming later this month, you might find that this fork influences the value and once its over, the value will dump and you start loosing on your investment, unless if you are willing to hold for long term.
Remember: Buy low, sell high
