Wasting my time?

Most of this Es season, I have been on 10m WSPR TX running 500mW from my little W5OLF WSPR beacon. It is on the same antenna that I used a few years ago on 10m WSPR when I was spotted in every continent.

Although I have been widely spotted across Europe and once in South America, I feel I am wasting my time. Although I know HF conditions are far worse than a few years ago on 10m, there seems to be a general lack of activity on 10m WSPR: I get far better results on 6m JT65. So, I shall probably stop 10m WSPR soon.
