"Unless Bitcoin tanks, lightning network fails, lightning network succeeds but leads to bank owned hubs, tether continues to print tokens and fails, bitconnect ponzi collapses, ethereum gets hacked, unfavourable regulation is passed, bitcoin energy costs get too high, bitcoin mining fees drop too much, Monero bulletproofs succeeds, optional privacy fails, exchanges require KYC/AML reporting and public keys are recorded by government giving them a list of every coin any person using an exchange has purchased, privacy coins are deemed illegal (coupled with KYC/AML exchanges), Bitcoin is found to be created by deep government like SHA256 or Tor, Satoshi sells his 5% (now 8% considering burnt tokens) stake in bitcoin, Large whales sell their stakes in bitcoin, other countries follow chinas lead in banning exchanges, central governments release their own tokens (like russia is planning to do) and require all taxes/rates be paid in that token, the internet becomes centralised due to the repeal of net neutrality laws, bitcoin or monero is found to be use din a major terrorist attack, bitcoin or Monero is found to being used more and more for drug trafficking, the 1% of fiat holders (rothschilds) decide to purchase a major portion of the crypto market using a small portion of their fiat, quantum computers developed by deep government are found to be able to match public keys to private ones... I will stop there because i have other things to do."
