Couldn't agree more! Folks either need a disciplined strategy like yours or just decide to not check prices hourly/daily/weekly.
As Warren Buffet likes to say: "People that think they can predict the short-term movement of the stock market — or listen to other people who talk about (timing the market) — they are making a big mistake."No doubt the cryptos markets are the same (it's still humans trading with a lot of emotion after all!)
Portfolio with diversification is the next area to work on.
