Depends on your timeline mate. If we are talking this cycle, then yes certainly they will last. If we are talking all the way through the next bear market? Certainly no guarntee, and only ETH I would feel confident making it through at this point in time. ADA definitely won't make it. The other 4 are all solid projects but seems like AVAX and DOT are vying for the same spot so likely one of those won't make it either. The other two at least operate on a different portion of the market which they could capture.
