Of course even major price correction is a perfect time to buy. Right now we are sinking and trading at around $8300. But if my memory serves me right, the last dip we see is around $5.5 - $6K, so its possible that we can go as low as $7K but we need to look at how the resistance at $8K will hold.
If it hold then for sure we are not going to as low $7K, so I would advise you to buy at the current price because for me its already cheap. You don't need to wait till the price goes to your expectation, otherwise if it didn't went your way, you already lose your chance to profit at the end.
