Every time there is always change, and we must be ready to accept the change, whenever there is always a chance to replace bitcoin with better coins, and whatever happens most important is that we always get benefit.
Chances are always there i think, and yes i agree on that whenever there is a chance to replace bitcoin with better coins we should always have the opportunity to benefit on it. For some reason i don't feel bad if there is no coin can replace bitcoin.Bitcoin alone is great and i believe on it.
Though i don't see that happening any time soon. No one bats an eye when an alt drops in value significantly even ethereum, but if btc drops, thr market goes crazy. There may not be an alt yet to generate a major effect on the market like btc yet
