Now I strongly advise you to wait. About $8000 should be thought about buying. I believe that we will correct it in this zone. Its just that such strong growth is impossible without a healthy correction.
I think the we have seen the dip already, bitcoin dropped $6500 this month and it pump to over $10K actually, so this is the time to sell now if a trader were able to buy at that very cheap price, 30%+ increase in one month is a great return already but at this time I am not anymore hoping a drop again as its a big news that drive this price to where it is now.
You can buy bitcoin anytime since you are HODLing your bitcoin for the long-term. You can buy even now.
People worry about buying bitcoin when they are buying bitcoin for the short-term - they buy low and sell high for easy profits.
