I'm negative 8k in my portfolio, you only lost when I sold

Guys, I just started buying Usual coins. Does anyone have any suggestions on what I can do to increase my earnings in the medium term?

Can someone help me, I just bought a $20.00 xrp coin on pix and my balance has not been updated.

I was wondering, why do they call small beads sardines and large ones whales?

Is it because whales swallow sardines or does it mean that sardines can come together to form a large school?

A whale is powerful on its own, but sardines together are strong.
