“不在银行账户上趴着” 我猜是指：把本钱从银行账户上取出，通过其他的方式获得更高的投资收益。 I guess: it means taking money out of your bank account and finding another ways to get a higher investment return . “在银行账户上趴着”是指本钱存放在银行带来的投资收益太低。 “在银行趴着”means: the investment income from keeping money in the bank is too low. 因为“趴着”的意思是：身体向前靠在东西上懒洋洋地，一动不动的状态。 在该句中引申为：没有产生任何明显的收益。 “趴着” means： your body is lying lazily and does not move at all . So in this sentence it means : no obvious benefit have been made .

But that doesn't make sense. Well, at least in Taiwanese Mandarin.

趴着 means stay/hold 表示不动的状态
