Ripple is a top coin and won`t die as it is backed by many banks. It is true that many other banks like JP Morgan
intending to run their own coin and there will be a big competition in that sector between them.
Competition is good and let the market decide.
If Ripple dies it will have a big impact on the market, maybe it will drop and investors don't trust crypto anymore, I hope big coins like Ripple continue to survive.
