Yesterday I participated in an ICO. I sent ETH to the correct contract adress and my transaction was confirmed. I also found my transaction on the ICO contract adress via etherscan. I then added a custom token in MyEtherWallet and the correct amount of tokens did show up. So far so good. I checked my token transfers via etherscan but any new transfer is listed. If I check the ICO adress via ethplorer it shows no transfers yet and also only three token holders. How can that be? Why do I see tokens in MyEtherWallet? Do I have the tokens or not? I am happy about any information.
