Given the fall in bitcoin in the past 24-32hrs, is it a good time to buy bitcoin?
Best time to buy Bitcoin is when you start doubt if it is good choice at all. When you will have zero doubt, then price is fro sure high. When you doubt, that BTC will get overtaken by some alt or when you doubt that some government will crash Bitcoin, then is perfect time for you to buy. Sad thing is that is psychologically hardest time to buy.
That is one very hard thing to do for someone who is going to be trying to go against what they feel at that moment. The best is not to even allow such a feeling to even erupt in the first place and to see the time when others are panicking as a good time to buy.
The way I see it is, once people are dumping, it is just a good time to buy as they have so much they are willing to give out at a lower price for you to buy.
