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 ?
Please no link
I have been using Binance and so far I have had no problems. Plus they have a very user friendly platform and they have a decent number of good coins that they support.
Another good one is Bitfinex. I used them for a while but they stopped allowing US customers but if you are from outside of the US, then that would be a good exchange to check out.
Using online one exchange is not a good idea, because some time you will not see a currency in one exchange which may bot be added there. Therefore you need to use different exchange. I think binance is a good option no doubt but if have an account in bitfinex it will also be a great idea because bitfinex is also a good and trusted plateform.
