Agree completely with these thoughts.

OP, have you considered a slightly different approach to buying bitcoins than in a single lump sum?
If you employ dollar cost averaging, you can avoid at least some degree of the volatility, and likely save yourself some stress...

I'm not sure if you are aware of the concept, but it runs something like this:
Take a fixed amount of money, every day/week/month. Any fixed period of time. And buy bitcoin with it.

The amount should be a small one, and the purchases should be continued at the same rate, regardless of what the price is.

So by averaging things out, you will (hopefully) avoid buying a "peak", and pay the average cost of a bitcoin, for the period that you were purchasing.
The only downside is that you also lose out on the opportunity to purchase any of the "dips", that occur, as well.

But it's likely a safer approach. I don't think many people here are consistently good at timing the market. If they were, they'd have tens of millions of dollars, and be on a beach somewhere.

Sometimes it is better to just take a safe approach.
