Trying to pick the perfect moment to buy Bitcoin (BTC 2.48%) or Ethereum (ETH 4.16%) isn't something you should be doing as an investment strategy. The odds of getting the timing right are simply too low to bother with.
On the other hand, dollar-cost averaging (DCA), where you invest a fixed amount at regular intervals regardless of the asset's price, can be a great approach that sidesteps the timing problem. But does it actually work to grow your portfolio?

This boring strategy can produce some exciting results
The appeal of DCAing is that it ensures that you regularly commit capital over time, buying more coins when prices are low, and buying fewer when prices are high, thereby smoothing out your average cost. The catch is that you'll never nail the absolute low with size, and in a sustained rally, a lump sum of cash deployed early would beat your returns.
CRYPTO: BTC
Key Data Points
A $10 weekly Bitcoin investment from 2019 through 2024 turned $2,610 into roughly $7,900, exceeding a 200% return in five years, and never disrupting the holder's sleep along the way. As of 2026, every rolling three-year-plus DCA window for Bitcoin since 2013 has ended in profit.
So, this strategy works, and, for the record, it's how I choose to invest in Bitcoin.
Ethereum's staking bonus
For investors building a well-balanced crypto portfolio over the course of a few years, the DCA strategy converts crypto's volatility into the mechanism working in your favor.
CRYPTO: ETH
Key Data Points
Ethereum offers DCA investors something Bitcoin can't, which is the chance of boosting returns via staking. By locking up your coins to help validate transactions on the network, holders earn roughly 3% in annualized rewards, compounding their coin count.
If Ethereum's price recovers, you benefit from price appreciation on coins you bought and coins you earned. It's the crypto equivalent of a dividend reinvestment plan (DRIP), and it's worth doing if you're DCAing into Ethereum.
