I think investing into Bitcoin is to be done with measuring success on long-term target rather than using market movement as your yardstick to measure success. Surely Bitcoin has the potential to do well in the long-run but if you're more focused on the market movements, you can be tempted to take short-term profits or even discouraged if the price doesn't go up as expected.

Definitely, it is always better to be actionable and start buying Bitcoin with available discretionary income having an accumulation target in mind, buying amount and long-term holding plan, building your backup funds alongside your accumulating Bitcoin to have a more successful investment journey, but in all these there's still no guarantee on the profitability of your investments into Bitcoin. Although Bitcoin has a history of good performance which can be convincing, but none of us can predict the future performance which makes Bitcoin a fair bet on securing your future financially.

Of course, even myself would say you've more chances at success investing into Bitcoin with a long-term plan when compared to those having decision fatiques and not wanting to jump in and start buying Bitcoin, but no one would offer or guarantee you on the profitability of your investment even though it's what we are all wishing for and anticipating that Bitcoin price continue to go up in the future.
