in my opinion bitcoin will not easily end, bitcoin will always be there and bitcoin will still be useful bitcoin could be one of the solutions in the future by improving the existing payment conditions in the world.
I do not that it is so easy to happen. Bitcoin is the strongest crypto currency and even the investors are making it more stronger, bitcoin will remain forever and not a single altcoin has so much potential to replace bitcoin. In fact bitcoin is the founder of all the crypto currencies and therefore it will always remain as number crypt currency.
