I believe that at this point you should not continue to buy bitcoin, you can see that bitcoin prices are adjusting up slightly in the past two days but now bitcoin prices are facing a very strong resistance at $ 6600 level. Therefore, I believe that the bitcoin price will be able to continue to decrease at any time so you should not keep buying Bitcoin at this time, the risk is very high.
But what's a bigger barrier: the 6600 resistance or the 6000 support? I think the support will hold out much longer than the resistance simply because there are miners standing at that level too. No one wants to see bitcoin turn into ethereum, so they'll defend that level to the death. Just look at the miserable state ethereum is in now because it's too damn expensive to mine.
Sure, 6600 might hold it back for a while, but I don't think for very long. If it's too high for you, wait until it bounces (if it bounces) back down a few hundred and buy. But what's a few hundred in the grand scheme of things?
