I think it's better if you buy bitcoin now if you have the capital but don't buy them all in bulk, diversify or divide the budget you have intended to buy bitcoin and buy them everytime the bitcoins price dips. That's called averaging too.
Yes I also think like that, the prices have decreased very much in the last few weeks. I think if we buy bitcoin now it will be able to get profit when the price goes up even though the price is close to $ 2000 but I do not think it will be under $2000.
And the happens you think can't become true is happening in past days. The price of Bitcoin had crash to $1900 and still around in this price 3 hours. But then, the price recovery very fast to $2000. I guess in next time we still have a crash make the price falldown to $1500 or $1200
