Short selling or even going long on any memecoin is straight bananas. When the market is moving it rises and dips so much that unless you have an endless amount of collateral you will be broke so quick. I wouldn't recommend margin for any altcoins. Money can be made but it's much easier to lose it all with margin.
This can be anticipated by using small margin in your position but also having high margin funding in your cross margin account, even if the coin somehow goes against our expected direction, we can still maintain it.
the reason why many people are liquidated because they right off the bat using 100% of their margin and over leverage, this isn't good practice because at the slightest price movement they can be liquidated, future trading requires good money management.
definitely not friendly for beginner, even more so when we are trading meme coin in leverage, we know meme coin in general are crazy with price movement.
