Well you might have missed the bottom at $15,500. But in any case still a goo price to invest, projection for the next bull run is 6 digits, $100k-$200k so you can still make a good profit if you invest right now.
The problem with all those who were waiting for the
"bottom" is that various
"experts" predicted $10k-12k, and the current price does not quite match what they expected, so many now have doubts like the OP. I can understand someone's hesitation if they want to invest a lot of money and maybe buy 0.5 BTC or more, but most of those who waited for the right moment invest several tens or hundreds of $ and actually will not save any significant amount in such calculations.
Right, it's really hard to time the bottom specially for those who are listening to this so called 'experts'.
When we reach $17,500, they said it's the bottom already, and then FTX fiasco surfaces pushing the price to $15,500. But if it OP bought at this price, just might be matter of months to see his investment double if we are going to continue with this bull run to $30k.
Again, not too late to invest for me as I'm looking at 6 digits as the next ATH.
