As crypto becomes more mainstream, we'll be able to buy goods and/or services without the need to exchange for Fiat or use a debit/credit card. Imagine living entirely off crypto alone. It would be a dream come through.
even though it will be amazing to see that coming to reality, it doesn't look like what is going to be very convenient for the larger population because adoption is still an issue and the rate of knowledgeable people that are comfortable enough to make use of it for such transaction is not all that much. with time when the rate of adoption must have increased and the commoners must have started making use of it for most of their needs, then we can see the possibility of it coming to fruition. 2025 doesn't look possible for crypto to go mainstream to that level except for those that are already in the system right from time and are familiar with the process that makin use of it doesn't look like a big deal.
