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.
