As much as I like to argue against Bitcoin, this article is stupid or to be more correct the author of this article has no understanding of currency despite claiming to be a senior economist.
Not crypto (i.e. BTC) is the problem, but the gov/fed printing more $ is.
Money is just a unit in which we measure how much value one has generated for another person. If the gov prints more of those units they change the scale and basically rob from everyone who uses that scale to store his wealth (say surplus or unused/unclaimed value from other people) in. If now some people start to create a new scale for measuring that value of goods and services like BTC or in our case XMR, we just quit getting robbed a second time by the gov (first time is through paying taxes).
I only used retoswap.
The trade was legit so no complains there. You can see the stats of this instance on haveno.markets.
