Lately, I've been torn between grid/DCA and a single trade — which is more suitable for someone like me with shallow sleep... Honestly, a single trade is definitely satisfying, but the first thing I do when I wake up at night is reach for my phone to see if I've been stabbed in the back; my mindset is directly influenced by the market.

Grid/DCA is like splitting emotions into small parts; whether I make money or not is secondary, at least it doesn't make every candlestick feel like an exam.
The on-chain MEV and fair ordering system have also been heavily criticized recently; retail investors always feel like they're always last in line, and larger slippage makes it easier to impulsively add positions or cut losses.
Right now, I use the simplest method: split orders into smaller parts, prefer to be slow, and treat delays and fees as tuition — better than reckless trading.
What I fear most isn't missing out on opportunities, but sleeping peacefully.
