It cannot be denied, the chance to get profit between you choose altcoin and bitcoin is same. Maybe you just lucky to choose some altcoin that you invested such as you bought BNB in a few years back then you compared it with bitcoin. Clearly, it depends on someone's ability to know or to predict the potential coin itself. If someone just depend on other people I mean when one of the altcoin price up so as many articles and some thread who discuss it in this forum then he buy it without to knowing what the coin as whole, then just give him a time to through failure that they will experience.
