I've also seen several Reddit comments from people saying they are seeing local businesses go from accepting it to no longer doing so, saying nobody was using it and it was a chore to train employees for no results.
Nothing like posting some links to give credibility to your assessment.
Anyway, even if I'm bearish on the short and median term, I'm positive in the long term. Rome and Pavia were not built on one day. To have already some major retailers accepting bitcoin is a success.
By the way, one of the basic rules of trading is: avoid to buy anything that didn't go the way you were expecting just to lower its price in your portfolio. You already bought at the wrong price a few times, so probably you are going to repeat the same mistake. Don't fight the trend by doing trades against it. At least, wait for serious signals of reversal of this bearish trend.
