For this argument to be compelling you would have to demonstrate a reasonable justification to assume that the number of sellers who accept bitcoin will not continue to increase and the ability to use bitcoin as a consumer will not continue to become easier. Unless you can provide a good reason why the trend will stop, then you are just blowing smoke.
In fact, my guess is not that you can provide any compelling reason why the number sellers who accept bitcoin will not increase and why the ability to use bitcoin as a consumer will not continue to become easier, but rather that you are attempting to actively work against these things occurring. You don't want bitcoin to succeed, and so you post negativity and implant negativity as often and as many places as you can, to actively work against it's inevitable success. Yet I haven't the slightest idea why you would want to do so
The only possible explanation is both a complete ignorance of what the Federal Reserve is and how it works and also a complete ignorance of what Bitcoin is and how it works. One is a cancer and the other is a cure. You are fighting the cure and protecting the cancer.
