Here is a very interesting reddit post by a user of forum u/werd22190. He started to buy Eth weekly not a long time ago, went through peaks and experienced a fall from 1300+ to 400. What made his portfolio still bringing positive returns now is DCA!
“I started an experiment (to prove DCA to myself) at the beginning of the year: deposit $50 into GDAX every week and buy ETH as soon as it arrived, regardless of the price.
A new $50 transfer was initiated as soon as the last one arrived. Bank Transfers took 6-8 days. I avoided all of Coinbase’s fees this way to get the most ETH per $.
Edit: a lot of people are calling out Lump Sum being better than DCA, which is true. However, I don’t have thousands of dollars sitting around. This is money I’ve budgeted from every paycheck to put into crypto.”
