Yes. The problem is in this ICO bubble start ups were given a lot of money with essentially no product - development time is needed. To further compound this problem is both Bitcoin and Ethereum have had a major boom. So the opportunity cost of holding tokens such as Mobilego, Bancor, Stox, Monetha, Sonm has been large. Its caused people to sell off tokens at a loss to try and recoup money back.
With the market being very bearish right now I can quite easily still see more downside for mobilego - but it is probably not worth selling now.
The last part of your post is decisive. It is probably not worth selling. Selling now is nothing but a big gamble to me. Mobilego has a concept in place and I am positive they will deliver on that. Better just forget about your tokens for some time and wait for serious development progress. Buying and selling back and forth between BTC/ETH and tokens like Mobilego can also lead to serious losses.
