I am doubting between buying more now at 9500-9600 or waiting to the correction.
My question to you is: were you buying bitcoin when it was getting pounded down to below $7k? That would have been the ideal time to be buying, whether you're looking for short-term gains or investing for the long term (IMO). If you're wondering whether you should be buying bitcoin when it's on an upward tear, you might have missed out on the best opportunities already.
However, I do think bitcoin is going to go higher--$10k within a very short time frame isn't out of the question, because as I'm writing this post it's above $9700 right now. So even if you didn't buy when it was low(er), I don't think it would be a bad idea at all to buy now. You definitely don't want to miss out if we start shooting past $10k, nor do you want to wait until bitcoin's price is near its peak (wherever that may be).
I didn't buy at 7k because I haven't had the money available. Unfortunately I wanted to, so I have seen the opportunity passing in front of my eyes. But its now when I can buy so I'm trying to choose the less catastrophic entry.
