But it is better to split the coins and not transfer coins with an unclear history to a centralized exchange.
The time has passed when you can transfer any coins from wallets to the exchange.
Till date people are still transferring coins from wallet to exchange, since it's not a mixer where you can mix your coins to different wallets, i want to know the possible means you can make a coins to land at exchange without transferring it from a wallet to an exchange, I think i demand more clarification from you.
