I've only been in crypto since 2017, but this still seems like a completely reasonable and healthy dip to me. Personally I've been waiting for a pull-back since $30K to average more into Bitcoin but that never came. Now I'm just looking at accumulating more Ethereum given it's still at a discount in comparison to BTC premium right now.
I won't be surprised to see Bitcoin below $30K, even though I realise corrections are usually only upto 35% in bull markets (which we are clearly in), I feel it's possible this extends to 40% towards $25K and given how parabolic prices have moved, I'm not ruling out a 50% correction to re-test $20K either.
I consider all of these lower prices as final opportunities to buy Bitcoin before it reaches 6 figures however.
