Yu kw, if you have $10k in pure discretionary income and no pressure elsewhere, going in heavy during a dip might not be a bad move..
Yes it's not a bad idea, but if their is no dip then, are you going to seat by and wait?
If you really want to invest in Bitcoin and you are only thinking long term, buying at the dip as you are only emphasizing on now is not the best way to go about your Bitcoin accumulation, just buy regardless of it current price because in the future, this current price will be too cheap when you reflect back.
If I were in your shoes with $10k right now, I wound probably put in like around $3k–$5k if I feel the market is offering a solid discount, but i would still hold back some to DCA over the next few months. With that, if the price drops more, I will not be stuck watching from the sidelines.
Looking at this your statement here, it looks like you are trying to outsmart the market, which is almost impossible, you can't be acting like a trader if you want to be successful in your Bitcoin accumulation journey because you may waste valuable time that you should have utilized properly.
Buying the dip is never a problem, the problem is waiting for the dip, and what you are implying above is that you will be withholding part of money you intend investing in Bitcoin with the expectations of buying the dip, it's not a bad idea in my own opinion if it's being done with your reserves funds when it comes, but waiting is a no no in my own opinion.
