I deposited 41 CGA to Poloniex but it hasn't shown up yet after a few hours. What's going on here?
Same here. No worries, just be patient until Poloniex is on the right chain, then they should show up.
Remember - when you transfer coins it is not like your regular coin wallet where you give money to another person
and if he runs off with it, it is lost. When you send crypto to an address, what really happens is that you register
in the block chain that the sending wallet's address is debited with the amount, while the receiving wallet's address
is being credited.
So, no matter whether the receiving wallet is online or not, the transaction is registered in the block chain.
As soon as a wallet that uses the Private key belonging to the receiving address is synchronised to the block chain,
it will show the credit that is in the block chain, that is how you can "receive" the coins, even though the transaction
really is only in the block chain. I regularly send coins to my wallet without having it open on my laptop. When I
synchronise my wallet a day later, it will pick up the info from the block chain and show it to me - your wallet is
essentially only a user interface into the block chain, showing transaction made for the address(es) that are present
in your wallet.
As long as the transaction of sending your 41 coins was registered in the block chain (use the explorer to see them,
you can see the amount and the receiving address and whether there were confirmation) then they are in the
block chain and Poloniex will eventually show them.
As I said, I have the same issue - the block with my transfer of 5 hours ago to Poloniex has over 100 confirmations in the block chain,
so it is just a matter of waiting till Poloniex synchronizes their wallet to the correct chain, then the coins will show up there.
Hope this helps.
