Also one of reasons is that it is lacking some liquidity or volume which simply means that there arent much people who had been trading on this platform in Dogecoin which its understandable that
liquidity is absent.
Liquidity is definitely the reason behind all of that. If you go on the orderbooks this is made very clear. Maybe a super good price for a tiny amount of DOGE and then they next order is way below. And by the time you discover that, plus the commissions for such small amounts, then you're done.
Even on DEX you can get done if you don't check price impact properly.
