According to reports, Bitcoin has almost reached to to it's peak. But it's expected to go $5.2K per BTC in next one year. During that time, it's also expected to decline to $2.2K during this year.
In my opinion, it's not good time invest in BTC. Rather, you can catch up with second rival, etherium. It's currently fluctuating around $300 per ETH. It's good to invest in ETH. But, as a good businessman, you should not stick your investment to one horse. You should also invest in ripple, a standardchartered backed crypto currency and third top horse in the race. Currently you can buy it a lot cheaper.
