Also here many accuse Cryptopia of theft, but tried to prove it? You, as a developer, probably can trace this to where the airdrop leaves. If there is reason to believe that they go to the purse of Cryptopia, then this should be shown on a general review and take action.
Also, you will agree that if, for some reason, Cryptopia has delayed the transfer, then you do not pay the airdrop. If we assume that Cryptopia is not to blame, then the developer benefits from the fact that the airdrop did not come.
I do not blame anyone, I just conducted a logical chain. If Cryptopia steals, let's prove it or we'll look for the reasons for the delays in the other!
And what if you prove it? What do you expect will happen?
You cannot do anything until you have alternative, and if you had alternative then you would not need to prove anything in the first place because first time that something like this happens people will just stop using Cryptopia and transfer to another exchange that has normal withdrawal time.
