Honestly it's also happened to me, almost everytime when i'm buying a coins or tokens, it's value are start to decreasing. Day by day i'm waiting and keep hodling, and the value starting to recover, and I decide to sell that assets in around +5%-+10%. And after a couple days & weeks, the price is pumped like crazy.
The coin that i bought is NEXO, buying at 740 sats and sell at 820 sats, and today the price is at 2655 sats.
