I think now would be a good time to buy bitcoin especially if you are into long term. Bitcoin is still cheap and we won't know after a couple of years it'll double the amount of what it is today, so if you're a risk taker then now would be a good time then.
long term: doesnt matter when to buy.
short term: might go lower. Someone is building huuuge sell walls - shorting btc with high volume.
those whale traders wanna buy lower and they will buy lower, since the whales make the market follow them.
