Now is a great time to buy bitcoins as the prices are low. Bitcoin made all time highs as at last year and since then, the market has plummeted and this is a great time to buy bitcoin at a discount as Bitcoin is one of the best investments to make in 2018
I do not think you should buy bitcoin at this time, you can see that bitcoin prices are constantly fluctuating and after touching the $ 8500 level is currently correcting around $ 8100. The price of altcoin is down sharply, so I believe that at this point you should only invest in short bitcoin and should wait for bitcoin to fall to $ 7900 to buy the bitcoin for the best price.
