well that is why i store my really long term coins at my wallet.
but i also day trade. there are times when i want to sell then because of confirmation time someone dumped ahead of me
is trex more secure than bter? or maybe hacker will only steal btc and not other alt
Bter has been hacked and as far as I know Bittrex has not been hacked yet. Most of the time if an exchange gets hacked only the high value coins get stolen. If you are trading in low value shit coins they are unlikely to be stolen if an exchange is hacked.
There are no guarantees though, when Cryptoine was hacked some shit coins were stolen along with the bitcoins.
