Unfortunately many of the projects were like that, and people realized it too late and that resulted with bad returns for many people. I do hope that everyone gets a better result, and they get great airdrops and tap to earns, but so far we haven't seen much.
Even the ones with 100+ million members, ended up with just a few dollars as a reward, and not only that but the token price crashed after a week or two and that meant even lower rewards. So long story short, we can't really keep having hopes for tap to earns, unless they show otherwise, so far there were literally just one place that paid well, everything else, hundreds of others, failed to give any decent return. This is why people stopped putting effort into them.
Nothing in the crypto world will go on forever, there are trends and then they die, this was just another. So we shouldn't consider this to be a big deal because there will be more and we just need to find the next wave. Think of yourself as a surfer (if you chase these trends) and as a surfer, you ride a wave, then go try again and find the next wave and try again.
Sometimes you crash hard, sometimes you just surf very well and get to the end line. Do not be worried about having anything like this because it is not going to hurt you but if you can do this then you are going to profit and if you cant then you just get back on the board and try again later and hope that this time you will do much better. If you can do this then you are going to benefit, because learning takes time but after you are good then everything is better.
