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.
Now of course the whole market jumps up and down, in such moments in the market it is best to sit quietly already purchased coins and do not twitch. I agree with you, it is easy to lose and just did not get the profits.
