in my opinion everything will end that is when the doomsday comes, but if bitcoin dies besides because it seems to me it won't happen because bitcoin has a strong fundamental and has become a part of life for many people
Yes it is impossible that bitcoin can be easily wiped out of crypto market. Today everyone is familiar with Bitcoin and most of the countries started accepting as for trade buying anything and paying through wallet in btc. so it is very rare case that happen but i don't think bitcoin will be completely vanished out of market.
