The only thing I'm kicking myself for is not cashing into either actual USD or just USDT (for all the scam worries it still holds its peg quite well) while my holdings were higher and then buying back now (or continuing to hold the cash). But I've kicked myself on that for many dips, and realize I really just don't want to fret over every dip whether I'm getting the right moment, especially because I often do not have good timing and lose some. I'm mostly content with holding through as the general trend, IMHO, remains on the up and up year on year. Right now very much looks like a great time to get in, accumulate, or buy back in. Me, I'm just annoyed that I haven't maximized my gains through swing plays, but day trading often requires far more attention than I can often provide if I'm going to do my actual job well. I check often but I often miss what I knew would be the best timing. Admittedly I might try some more because I've been holding to myself some personal charting guesses that have been right calls if I could have convinced myself to make them, but I worried I'd miss the start of the downswing due to work or other circumstances. When I have tried, that has happened, and then I end up holding too long thinking I'm reading a bounce correctly and then it's a free fall. Welp, time to hodl the bag I guess. Unless it's too scammy, then I'm probably out.
One thing I wouldn't mind is for BTC to remain on the up and up, because if you watch when the entire market drops, not only to USD values drop as BTC drops, but most alts continue to lose ground against BTC as well, so their USD value drops are far more significant. If you ignore the USD values and stick to BTC values, you'll see you can actually make far more if you weather the BTC storms, as you'll make more in BTC and when it inevitably begins to rise and the alts begin to rise against BTC, that's when you buy back in. As BTC rises overall you'll find your gains moving far more. That's IF you can more or less actively day trade. Still nearly impossible to time the major spikes, they can sometimes start from moments like right now where there is tremendous squeeze pressure. Theoretically it could rocket in either direction, a huge candlebar, but I'm guessing more generally upward than down from here.
But as I'm playing entirely on house money now myself (I've cashed out original USD values), I also don't mind weathering the major storms like right now because I don't have a pressing need to worry about withdrawing any more cash, and I strongly suspect the general bull market is going to continue, despite the well-needed correction) as that last surge was entirely too much too soon, breaking out of the channel. On longer scales, it has returned to the channel and hasn't broke the southern boundary. It tested that boundary but shows some promise in retreating from it, retracing from what will likely have been decided is an over-correction.
