Bitcoin is already unique, I understand what you mean by looking for the next altcoin with a strong upside potential.  I'm always ready to find it, too.  Lol, There are many coins that have very strong value expansion when linked and suitable for chains of events.  Currently, I am quite interested in AAVE, BNB, Uni, Cake, I have put them into long-term accumulation plan.  I know that Grayscale will extend a trust fund for defi, if that happens, Uni, Cake might also make x10.  haha
