Is it safe?
I can confirm that personally I was able to buy over 80,000 KDA on Hotbit and successfully withdraw It to a Kadena Mac wallet Chainweaver but not without minor hiccups.
The problem are withdrawals. Long story short it's about cross chains transfers... that are hardly happening now without some coding.
That's why when you look at Hotbit cold wallet they had run out of coins on chain 0.
Therefore if you attempt to facilitate a withdrawal to your chain 0 account it won't happen. That's why Hotbit added a field where you pick the chain and you should try withdrawing to chains 1 or higher.
Their support is moderately slow but If you keep spamming them they will fix that for you.
Just remember that in the Chainweaver wallet the field which says Kadena Address isn't actually your real address. The real address which you provide for Hotbit is actually your Public Key (and your account name in the same time).
HotBit
When it comes to trading on Hotbit you must know that the volume is measly, even thou we have had a bit of a breakthrough in that area today with total volume of KDA/USDT and KDA/BTC pairs excessing 250,000 coins and $60,000.
You will encounter a lot of bot activity and your best bet would be placing low bids in hope of some miner filling your bag. Tho I'd watch the order book closely and pay attention to news since it may advance onto completely different price levels anytime. Since there is enormous OTC demand and VC's and Chinese whales are taking any coin off the miners hand like mad dogs.
