I guess that by "now" you mean yesterday.Every time is the best time to enter in bitcoin.
The price crash is over,but the price is again under 4000 USD.That doesn`t matter anyway.
I see many threads asking "should i buy now" posted by newbies,but you are a Sr.member,you should have more experience here.If you have money and want to buy,just buy ,don`t ask.
Don`t seek advices about what to do your own money.
Exactly because the fact that you have more knowledge about bitcoin and you see how it really works. So why are you still asking for it? Well, if you want an answer the perfect time to buy bitcoin or emter here was when its price drop. When it happen grab the opportunity and hold for it until it pump again to get profit from it. I can say everyday was good to buy bitcoin why? Just simply because of what I see in bitcoin that it continue to increase right now.
