ZCL / ETC Hardfork-Airdrop

As we can see big exchanges like bitt__x are not going to support very awaited hardfork - airdrop of good cryptocurrencies like ETC and ZCL... it does not seem good sign for trust that traders do on such exchanges. from next time traders may think twice before trading on such exchanges for long term.
Also as every day over loaded new icos are coming in market , traders are getting much confusion on it. which is best ico? team is good or not? will be profitable or not? investment is secure or not? such kind of questions are harrassing to traders too..
so how to trade well? if in future big exchanges do not support good hard fork or airdrop, they will loose trust of traders who trades on their exchanges...
After not supporting good hardfork or airdrop , big exchanges have made traders to think twice to continue trading on such exchanges for free additional profit in form of free tokens...???!!!

Please comment your opinion too....

Thanks.
