Bittrex is a well-known old exchange, I have used their service for 3 years. The delisted altcoins are pumped at least 3 days before the announcement about the delisted coin list. The support team solved my problem after 4 hours I created the new support ticket.See full review

The best wallet for checking the phishing websites is the MetaMask wallet, there is no better alternative compared to competitor's wallets.

The smart contract call feature is very useful on the contract address type required payment sites. See full review
