Buying bitcoin for now is kinda risky bitcoin @40000$ is to high, but if you find a great support in bitcoin well I think invest because it will not go deeper, and as many groups in telegram said it will go 42000$ this week or this month but be careful and #DYOR it is OP's money after all...
I don't think it's too risky to buy Bitcoins now, I know it's around it's new ath of 40-41k, but if you're not a short term Investor, and you're buying to hodl, then there is nothing wrong in buying Bitcoin at the moment; I believe in the network cause I've studied it's historical price movement and the influx of institutional Investors to the network is also a plus, and I sincerely doubt the network will be struck with a severe plunge; corrections in price is definitely going to happen, but that shouldn't worry anyone, except the newcomers.
