The Vibe: Putting a big chunk of money into crypto all at once instead of spreading it out.
The Details: Lump sum investing means buying with one large amount at whatever the current price is—betting you’ll get in at a good time (or just not wanting to wait). It’s the opposite of DCA (dollar-cost averaging). In theory, lump sum often beats DCA over long periods because markets tend to go up more than down, but in volatile crypto, bad timing (buying right before a crash) can hurt a lot and cause emotional stress. Many people prefer DCA to avoid the regret of a poorly timed big buy.
Pro Tip: If you have a windfall or strong conviction the market is low, lump sum can work great—just make sure it’s money you can afford to see drop 50%+ without panicking. Most beginners feel safer (and often do better psychologically) with DCA.
