Have you discovered some token were disappearing within the market at this period. Such as Bitboost just suddenly disappeared away from market without prior awareness. Should that be? Is that not a cheat?
There are many reasons why a token sudenly dissapearing, maybe there is no volume trade on the token and the exchange delisted the token.
Or there is no single update from the project, so the token looks like abandoned by the team and many other reasons.
Yeah, if there's no volume and no current movements happening around, the exchange will delist it, if you are holding those coins you need also to be updated in order to follow the movements of certain projects, there's no chance to sell it out after the team left it and no exchange that will cater the
trade, best to liquidate before things happen.
