Realizing the Cost of Trading Around Core Positions

Been thinking a lot lately about how I've handled some of my $ETH and $BTC exposure, specifically the temptation to try and trade around a long-term core position. I've found myself getting chopped up pretty badly on multiple occasions trying to be 'smart' and optimize returns by selling a portion on a pump and buying back lower. The issue isn't necessarily the premise, but my execution and the emotional toll it takes. More often than not, I've either sold too early only to see the price continue higher, forcing me to buy back at a worse entry just to maintain exposure, or I've bought back too early on a dip that continued to dip, leaving me underwater and tying up capital. It's become clear that for my core holdings, the mental and actual costs of trying to scalp or swing trade around them frequently outweigh any perceived benefit. The commissions add up, the stress of constantly monitoring charts for entries and exits is draining, and the opportunity cost of simply holding through volatility is often overlooked. It's a tough lesson to internalize, especially when you see those big percentage swings and feel like you're leaving money on the table by not being more active. But honestly, the peace of mind from just letting my long-term allocation sit is becoming far more valuable.
