guys, whatever you do, DO NOT EVER USE HOTBIT. i sent coins there. it mentioned payment id but said "optional" so i didn't input that. my coins never showed up. so i contacted support and they asked for txid's which i sent them, they then asked for screenshots and tx id's again with transaction history which i again sent them. they then asked for various other screenshots all of which i sent them. you can clearly see my tx's on the blockchain. they have no wsaid the ycan't verify them and will send them back to the original senders wallets. i said ok do that then. that was 1 week ago and still no coins back in my wallet. now they are saying it will take up to 3 MONTHS. months to send my coins back? what a joke!!
