I do not know if I laugh or kill someone jajajaja, the truth is that I transferred 100 XLC to Cryptopia and they arrived without problems, then I sent 50 XLC to cryptopia and they arrive without problems, I am deigned to send me 2500 XLC to Cryptopia and they block me the coins , the wallet generates a TXID but with a question mark "?", I waited several hours and the transaction never appeared, after a couple of hours I had to restart my lapto and when I went back to my wallet I asked for a password , something strange because I never configure it with a password, after that I had to reinstall the wallet and with the backup I had to synchronize the wallet, I reviewed my transaction history and it turns out that there are 100 and 50 that had already been confirmed , but the 2500 disappeared and my balance is 0, hahaha well done by developers, I was scammed.
Scammed by who? Does the wallet show a transaction for those 2500 coins going somewhere? If not, the coins are still yours. If TX shows going to Cryptopia, you need to wait and/or contact them (yesterday they had XLC deposits paused again). If you see TX going somewhere else, then yes you've got scammed/hacked (or how you want to call it) and the coins are no longer yours.
You just need to understand the blockchain... if you have coins in your wallet, the only way for them to go elsewhere is via a transaction (and fully synced wallet would show you that).
