The world dependence on the dollar is certainly the biggest advantage of the dollar owner, the value will continue to rise so as to make many countries try to leave the dollar and look for other alternative payment systems, the presence of cryptocurrencies should be a solution for the world to be able to solve financial problems.
We are hoping that the dollar performs very badly and people look for alternatives but we probably need a complete collapse of the dollar if we want to achieve complete mainstream adoption which is probably unrealistic. The best we can hope for is probably being used as a store of value instead of a daily currency. Competing with the dollar for transaction fees is just not going to work because the dollar does not rely on miners and do not need incentives to allow transactions to be sent. We will always be battling that because we cannot make 0 cost transactions but bitcoin makes it easy to store value from a third party and with banks that go bankrupt with the current crisis will help the adoption of btc and force people to look for alternatives.
