I was prefer poloniex because was my best palform but when some one hack my acount and withdraw all my money i leave then i was go to bitrix but they also make new rules about active acount so now my question is what is best palform u can deposit ur money in it without scare and why ?
if you're switching for the reason of security, whichever exchange platform you choose doesn't matter much.
why? because you said your account was hacked and most likely the fault was on your side not the platform
so even if you use the most safest and secured platform,
you're still susceptible to hacking if you don't guard yourself from any attack on your side
