I just remembered that the chain is congested again. Trading isn't just a click and it's done... After entering the mempool, it's like standing in line and being penalized. If the gas/transaction fee is too low, it keeps getting pushed back, and someone ahead adds a higher fee to cut in line, leaving your transaction stuck. The most annoying thing is that with perpetual contracts, traders get emotional and want to add to their positions, but on-chain margin transfers can take so long that I have time to cool down (sometimes it's a lifesaver). Recently, before and after the upgrade/maintenance of that mainstream public chain, people in the group are guessing whether projects will migrate. I prefer to watch the congestion and confirmation times first, so I don't find out too late that "it hasn't been on-chain yet" when I actually need to use it. Oh, and I always take screenshots of stuck transactions... as proof to cool myself down. If I lose money, I just follow the rules and stop trading for a week first.
