$RIVER 做多又吃又拿 - This phrase appears to be slang/colloquial Chinese that doesn't have a direct equivalent in standard financial terminology. It roughly translates to:

long positions while getting multiple benefits/advantages

or more literally:

going long, eating and taking (both profits)

However, if you could provide more context about how this term is being used in cryptocurrency or financial discussions, I could provide a more accurate translation. The phrase seems to combine market positioning (做多 = long) with colloquial expressions about gaining multiple advantages.
