This question have been anwsered a thousand time. The best time to buy Bitcoin was in january 2009, the second best time is now ahah Seriously, if you wonder if it is a good time to buy, it is not for you because you know little about bitcoin and investing.
Past is past Bro every one knows this truth. If you buy last year also it is a big profit now.
Buying bitcoins for high price is upto your risk. Bcz now the price is very high.
